Is money for a prize for my scientific work (which is my job) "like my main job"?

[kdm]

I was awarded a prize for my scientific work. I received a 1099-MISC for the prize money. When I enter the information, turbotax asks me if this money involves "work that's like [my] main job"? How do I answer this?

Which box on the 1099-MISC was the income reported in?

Box 3

Answer no.  TurboTax is trying to decide whether this is self-employment income on which self-employment tax should be paid.  It is not. It does need to be reported as other income on Line 21 of Schedule 1, but not on Schedule C.  Keep answering questions that make this "one-off" income to steer it.
