The issue is which state is your state of domicile. Your domicile is your main, permanent home, whether owned or rented. If your main home is in NC, and you are in TN only on a temporary or transient basis for work purposes, then NC is your state of domicile and all your earnings are taxable by NC.
TN does not have an income tax on earnings from work.
