I received a 1099-MISC for a sleep study and got paid for "sleeping" while hooked up to wires. Was this the "service" they are inquiring about in order to earn my check?

This was a medical research study where I spent 2 nights hooked up to wires, then went home for the day. That is all I did. The question on Turbo Tax was whether I performed a service for my money earned. Do I answer that yes or no?
