When filing North Carolina 2020 individual income tax return using TurboTax, my 2019 income tax overpayment credit to 2020 return is carried over to both 2020 Form D-400 line 16 as prior year tax credit and to line 21a as 2020 estimated tax payment, therefore double counted. Is this double counting correct for me to get more tax refund on 2020 North Carolina tax return?
In addition to the 2019 income tax overpayment credit, I made North Carolina estimated income tax payment for tax year 2020 in September 2020, but I find nowhere to enter this payment amount. Could you please let me know where to insert my 2020 estimated North Carolina payment using TurboTax? Thanks.
