I'm replying to myself because I don't know how to edit my post.
I ended up just putting everything together in one W-2 entry. I had 3 "Box 12 Code L" entries from 3 different states. TT balked at "duplicate entries" even though they are from individual states. I just deleted 2 of them and added them all together on one line. TT accepted that. I hope the government is accepting of it as well.
I'll update this later if things go sideways, hopefully not from tax jail.
Thanks for reading my word salad.
