Thanks, I had already followed the directions you cited. I claimed that the cost of the items I sold on eBay was the same as the proceeds, which, I believe we both agree, is the correct way to report this income. That's what I did for my 2021 return, and I had no e-file problems.
I did not claim a loss, contrary to the error message I cited.
I eventually overcame the problem, later this morning, by deleting the 1099-K worksheet. That action allowed me to e-file and, to me, this further suggests that the error message I received, repeatedly when trying to e-file, is a bug.
