How do I include my Tax penalty when I pay my tax ?

Turbo Tax said I could combine tax owed and penalty

What tax penalty are you talking about? If it is the underpayment of estimated tax penalty, this is found on line 38 of your 1040, and despite its location, it is rolled into the tax due on line 37.

Or are you talking about a different tax penalty?
