I am having the same issue. I tried your "solution" but it doesn't work if the taxpayer is getting a refund in excess of the amount to be deferred. I clicked on "yes" I want more time to pay, and I am told that I am not eligible. I click "Continue" it brings me back to the 2020 Deductions and Credits summary page. I cannot submit my taxes because of it tells me the number on Line 11 on the 1040/1040SR Wks is too large. It is "0".
I have spent hours trying to sort out YOUR software problem. If I can't figure it out in the next few days I will be requesting a refund and purchasing another non-TurboTax package. Would you please fix your software???
