Since you never established residency in NC, you will file:
1) a non-resident NC return, reporting all the income you earned in NC; and
2) a part-year resident return in SC, reporting all the income earned while a resident of SC, and
3) a part-year resident return in PA, reporting all the income earned while a resident of PA.
With TurboTax, you should file your state returns in that order.
My answer assumes that you abandoned your domicile in SC when you moved to PA.
**Answers are correct to the best of my ability but do not constitute tax or legal advice.
