How to pay estimated tax penalty (line 38)?

[Daniel_K]

I have an underpayment penalty on line 38 of my 1040. This amount is not included in the "amount I owe" on line 37, correct?

Turbotax generated a payment voucher for the amount on line 37 but not for the amount on line 38. How do I pay this penalty? Do I wait until the IRS bills me for it?

You only have to pay the amount on line 37 of form 1040.

Any estimated tax penalty on line 38 is already included in the amount on line 37.

See this IRS document, page 61.

The Estimated tax penalty on Line 38 of the Form 1040 has been included in the federal taxes owed or it reduces the amount of the federal tax refund.

@MinhT1 shouldn't it be line 37, line 38 is penalties only.

The penalty on line 38 IS INCLUDED in line 37 tax due.  Check, line 37 should be line 24-33.  Then add line 38.

Thanks all for the clarification! I followed @VolvoGirl's instructions and everything checks out - that is, it seems that line 38 is included in line 37 after all.
