State tax filing

Thanks again.  I guess my issue is just that TurboTax isn't doing a great job guiding me through this situation.  I guess that my main question on the the SC return, is the tax credit for NC already factored in or do I have to enter it somewhere?  What I have done so far is done my NC return (I didn't list anything about SC at all), I entered the information on my SC return saying that while I was a resident I paid XXX amount to NC.  After that, the amount I owe SC goes up significantly.  But I don't see anywhere for me to enter a credit, leading me to think I need to enter it somewhere.
