I had the same issue. I have a solar electricity system to even out my electricity from utility and what my panels produced. Sometimes, we produce more than we use, and the electricity pays us once a year for the excess and sends us a 1099-MISC with block 3 filled. No other fields are checked or have entry.
I went through the whole process of entering the 1099-MISC but it was the last question that triggered creation of SCHEDULE-C. So, if you are receiving 1099-MISC, don't check the last box where it asks, "Name intends to get this in 202X."
Took 3 hours to get the answer, so by the time a TT Expert called back, I already had the answer.
