not sure if I am following you, but sounds like you would prefer to pay the amount due at the State website rather than set up the payment within TT.
if that is what you are trying to do, then just leave the state return in TT as it is and DO NOT pay within the software. The State will see you have money on account to offset what the Tax Return states.
Alternatively, and I am using the desktop version, go under 'payments' and enter the amount and the date you are going to pay; that will zero out Line 27 of the NC return.
