I owe more than I paid with 4868 extension. I used IRS calculator to get amount of penalty and interest. How can I pay them with my final tax return e-filing? I know that TurboTax calculated penalty, however it is different from IRS calculator amount; I don't see a way to enter interest at all.

What is generally recommended is that you don't try to calculate any additional interest or penalty. Just go ahead and file your return as you have prepared it. The IRS will calculate any interest or additional penalty and notify you of additional payment due.

There is no way for you or Turbo Tax to calculate any interest. It is determined by exactly when the IRS get your tax due payment. Just let the IRS bill you for any more.
