You will need to enter all of your itemized deductions on your federal return. TurboTax chooses the deduction that is most advantageous for each return. TurboTax also determines what is more advantageous for your NC state return. If TurboTax is also using the standard deduction, it could be that your total itemized deductions might not be enough to make a difference on your NC return.
Before you start fixing your state return, look at your federal return again. Make sure you didn't miss any deductions that could have been included. After you review your federal return, select the State Taxes tab and review the state section. Pay close attention to the information, especially if you have made changes to your federal return. There might be new sections that need to be completed.
