TurboTax Premier didn't calculate that I owed the State of NC on the $80K Capital Gain from the sale of my home. But my Realtor said that I would be taxed by NC?

All the Capital Gain info. was entered for the Fed. income tax return. TurboTax said that amount didn't have to be reported. There was no option to re enter those figures for the State, as it simply pulled the Federal info to complete the State of NC return. TurboTax Premier is supposed to come with live support but there was no option found while I was filling out my return to ask this question. Is Turbo Tax Premier correct in not determining that I owe the State on the sale of my primary home, which I lived in for 4 years? My Realtor said I would owe the State.
