For the life of me, I cannot figure out what I am doing wrong while

I've never installed a door before, so any advice would be appreciated.

If by the "bottom of the door hits the striker side fist with about an
1" gap at the top" you actually mean that the bottom of the door hits
the "doorstop" and the top is 1" away from the top of the doorstop then
the jam (and probably also the wall) on the striker side is NOT plumb.
