There's 2 issues now.
1. The initial discussion about your interpretation being invalid. You see if an interpretation is valid I'm perfectly happy with multiple valid interpretation. Please don't mistaken believing a particular interpretation is invalid as a belief that there is only ever a single valid interpretation.
I would usually assume as much if my interpretation were received with anything resembling good faith. Instead, there's a great deal of misrepresentation going on, including the following:
2. The point you made just a few posts back where you argued that due to rules being non-restrictive and you being able to abdicate your particular way meant you were playing by the rules. In short that issue is as I stated "The issue is using the idea of DM abdication as proof that you are doing something by the rules."
This is an issue you've created by misunderstanding my argument, and despite my efforts to clarify my meaning, you've persisted in your misconception and are even claiming I made a point I haven't. If your intention isn't to misrepresent me, then I would suggest reconsidering what it is you
think I'm saying when I tell you it isn't what I said.
A level 4 Fighter player may declare he attacks the ogre 4 times with his greatsword. The rules restrict the mechanical resolution of that declaration to a single attack and damage roll on this particular turn (barring the extra attack feature).
That doesn't restrict the player's action-declaration, though. It just requires his/her action-declaration to be resolved over the course of four rounds and that the ogre will be allowed to attack in return.
So you believe the condition for the bonus action shove hasn't been met until you have taken the attack action on your turn. That's a good start. At least we agree there.
So you also believe you can't check whether you took the attack action on your turn until 1 of 3 things happen
1) you take the attack action
2) you take another action
3) your turn ends
I agree here as well. You even go on to say that ONCE the condition has been met that qualifies you to use the bonus action shove any time during the same turn. I agree there as well.
No, you don't. If I understand your position correctly, you believe it qualifies you to use your bonus action only in the part of your turn that comes after the condition has been met. I take the rule on bonus actions seriously when it says, "You choose when to take a bonus action during your turn, unless the bonus action’s timing is specified," and I don't accept the argument that the Shield Master shove's timing is specified.
What I don't get is how you are saying "ONCE the condition has been met" and then insist on being able to "time travel" back to a point before you actually met the condition and then claim that because you actually met the condition in the pre time travel timeline that you now have also met the condition in the post time traveled timeline even though you've still not met the condition in this post time travel timeline yet. How does your interpretation not essentially boil down to something like this?
Because there's no time traveling. Whether I take the Attack action on my turn or not is an objective truth. If I do, I have a bonus action to use.

In my games a turn is treated as a sequential series of events. Is it not treated as such in your game?
It is. The fictional events that happen in a character's turn happen in a sequence.
If it's not I could maybe see how your position makes sense?
I doubt you're trying to see how it makes sense.
