I don't have an answer on the Deferred Comp. W-2.
BUT
If you moved to NC in 2021, then part of the 1099-R distribution will likely be NC-taxable (unless it was distributed as a lump sum before you moved to NC).
Pension income is only taxable according to the laws of the state you are a resident of at the time you received the $$.
So if you moved to NC during 2021, and received monthly pension payments during the year, then any $$ distributed to you after you moved to NC are considered NC income, and are taxable by NC . You would have to allocate those $$ between the two states in each state's Part-Year tax returns.

IF you are continuing to get pension payments from that employer's plan, make sure they know you are residing in NC now, and start NC withholding to offset any taxes you may owe to NC.

The only exceptions to NC taxing those pension $$ are for certain Federal pensions (5-year vested by 12 Aug of 1989), and most standard Military pensions.
