Hey guys I am planning to add a USB and 12v outlet on top of the center dash (behind my built right phone mount)
I am thinking of using a add a circuit and tap it into passenger side fuse box.
I want this to be on al the time hoping to use a constant power. Any suggestion on which fuse to tap into? and which fuse amp should I be using for the project?

By the way I am already using 36 for my ham radio.

That list does not look correct. Nothing on your list corresponds to what I have in my manual. Also, 17 on your lists says HUD and I don't think our trucks have HUD.

For what you are looking for, #4 should be an always on 20A circuit that is currently not used by any other accessories. I used that for an always on dash cam.

The OP has a 2018 Gen2, so that may be where the discrepancy comes in. It appears to be the correct list for a 2018.
