State tax filing

Yes, as long as your total yearly income (that includes everything)  was above the NC-Limits for filing.

The NC filing requirements table is on this page:

The procedure for you, if you were required to file as an NC Nonresident...would have been to prepare your NC Non-resident tax return first, and then prepare your SC resident tax return after that.  NC taxes just your NC job income and calculates a tax 

........and then AFTER that, you work on the SC resident tax return, which calculates a tax on ALL your income from everywhere.....including the NC wages....but then SC allows you to take a credit for the taxes you let NC keep.  But the NC Nonresident tax return has to be done first to calculate that amount.
