Drug Trials?

Hello

I received a 1099 NEC from my drug trials, which involved just a monthly IV. $825 received.

Been reporting the last two yrs on schedule 1 other income. No issues with that.

Now I have 1099 NEC spot in  Turbotax, but wants to treat me as self employed. which strictly I may be, but this doesn't seem  to fit. Still tempted to report on schedule 1 and  send a copy of 1099 NEC.

Any thoughts?
