I found this in another thread at (https://proconnect.intuit.com/community/proseries-tax-discussions/discussion/deferral-of-se-tax/00/1...) and it seems to have worked for me.
"OK, I see how to get rid of the deferral I think. Putting 0 on Line 18 of that form isnt correct.
Go to the 1040/1040SR worksheet and scroll down to the Deferral for Certain Sch H and SE Filers smart worksheet looking box, Line 11 put a zero and nothing will flow to Sch 3 Line 12e.
If you do choose to defer, Im not seeing a spot on the Carryover worksheet for the deferred portion to carryover to 2021, so I dont think this part of the program is completely updated yet."
