Thanks, that worked. I gave it a "best" because I also had to delete two spurious Sched Cs it had created, and the check process wanted fully filled in. The form delete didn't work quite as described, I got a Forms submenu and then a list of forms on the left to view them, then deleted each Sched C when it was displayed (confirming when requested). But after that, check was error-free and amt owed was $0 as hoped.
Thanks to all who responded on this. My error was to (1) say I hoped to earn from the same source in 2021, and (2) say it was to earn money. I guess in this context "earn" involves employment, which this income did not.
