State tax filing

Occasionally, CA might send a letter to you sometime in late 2020 or 2021 about not filing CA for 2019....but you'd just respond to them that you moved to NC right at the 2018/2019 turn of the year .  Keep couple of bills or CCd account statement  from NC purchases right at the 1st ,+ or - a couple days to prove you were in NC then.  Rental lease....home purchase statements might be off some, but they shouldn't complain to much about a minor bit of slop.
