Hmmm... Let me know if you hear about anything for sole proprietors doing 1099 work that has evaporated...
(Thanks for previous suggestions too. Am still looking into online tutoring and such.)
I could probably get a “written notification” from my last “customer” stating why they were “discontinuing my services” as I was told on the phone, and I have my statement (1099-misc) for 2019, of course.
