D&D 5E Valor bard - fighter

[Barolo]

20th level fighter = 4 attacks.

+1 from Xbow master.

Already counted as the bonus attack action in my post.

Let me break it out for more clarity.

Attack action: 3 attacks because of Extra Attack (2)
Bonus Action: 1 attack because of Crossbow Expert

It was specifically said no haste or action surge. So what am I missing for the 5th attack?

Level 20 fighter:

Attack action: 4 attacks because Extra Attack (3) (from 5th, 11th and 20th levels)

I'm a dumb ... backside. Totally forgot the 20th level capstone. Sorry.
