1099 NEC Box 6
I did a few federal and state e-filing for 10 of my employees, just found out the state abbreviation I put in box 6 was incorrect for the majority of them. Since one employee lives in CA and the rest lives in KS. I switched to CA for that one employee, and I forgot to switch back to KS for the everyone else that came after.
Do I have to refile for everyone with the wrong state abbreviation? there's NO state tax withheld
