One more post, sorry to be annoying. I somehow was now able to remove the auto-populated number from Line 11 of Schedule 3 Part II of the1040/1040SR Worksheet. That then blanked out the number in Line 31 of my 1040 but kept the number I entered on Line 18 of the Schedule SE-T form and it added the money back to my 'Federal Tax Due'. So I should be good to go now.
SO I think that's the solution...determine how much of your income was earned after March 27 (using "any reasonable method") and enter it into Line 18 . Open the 1040/1040 SR Worksheet (by clicking View > Forms) and put a '0' in Line 11 Schedule 3 Part II. It looks like the tax forms should then be correct and you'll pay the full amount now rather than deferring.
Good luck!
