Steering wheel isn't returning to center/does this alignment seem fine?

Take it back and tell them! Make they correct it. The SHOULD have checked for damage.
What kind of box? Paper? cardboard? brick? wood? steel????

 

I wonder if when you smack the box in the road if something moved and did some steering shaft damage or misalignment which is a stretch. But that does seem awfully odd I mean the cars are not that weak in this area but I guess all that stuff does crumple in an accident so maybe hitting the box at that speed something bad happened That's crunch something enough where you're getting this resistance.

 

Take it back and have them fix it! In looking at your chart, they didn't change almost anything, just the toe slightly and none of the other settings changed. Kinda seems like a rip off...

Usually the part of the adjustment that gets the steering wheel spinning back on its own while driving forward is the caster and they didn't adjust that. But low tire pressure could slow that response down a bit...

They didn't do enough work on the alignment (obviously) and you deserve to get your money's worth. Take it back and tell them the caster is no longer what it used to be and the data on their alignment sheet is wrong:
