@Mark Brockman  If you go to the 1040/1040SR Worksheet for Schedule 3 (you can get there by going to Schedule 3, line 13z and clicking on the magnifying glass) then once you are on 1040/1040SR Worksheet find the Other Payments and Credits Smart Worksheet  that's between lines 12 and line 13 -    that is where you enter the amounts for line 13z    No override required.    

Federal and State income tax payments for estimates, withholding, extensions, and amendments should actually be entered on the Tax Payment Worksheet
