Just chatted with the support team on the phone. I followed the step-by-step guidance above and was still getting the Schedule C form -- which is expected for a 1099-MISC I guess. The support team helped me fill it out the Schedule C to clear the smartcheck errors...
Address questions -- use your home address
Business name is your own name
Business code is 999999,
Accounting method = Cash
Did you materially participate = No
Required to file Form(s) 1099? = No
I was concerned about this approach, but then they reviewed my actual return forms and the Schedule C questions properly reported the income as Other Income. That's good, and there were no errors after I finished that.
Hope this helps. Good luck!
