The amount on Line 38 of Form 1040 SR is included with the amount on Line 37, if you have a balance due. If you overpaid your tax, the amount you overpaid on line 35a will be the amount of your over payment on line 34 less your estimated tax penalty on line 38. So, you will be paying the penalty by a reduction in refund, or by paying the amount on line 37.
