Deductions & credits

I think I'm getting close to the answer. You say under "PAYMENTS". Specifically, where in the TT desktop tool are you referring to? Can the value under line 27 be changed there? I've done this a few years ago but can't remember where in the desktop tool I did it. 

I'm going through these gymnastics because I don't want to pay the state interest on amount owed by filing taxes by May 17th; although it's only a month after 4/15. I want to pay the state tax owed online at NCDOR on or before 4/15. THEN e-File both Federal and State using TT desktop by 5/17. The state that I e-file will be zero because of the amount I paid at NCDOR.

Although NC DOR extended the filing deadline to 5/17 without penalty on taxes owed, they are charging interest. Don't want to pay a penny more than what's owed. Thanks!
