Bought a Jenni O turkey not frozen,last thursdsy but it started to smell by Saturday a little so I put into t.

Hi! Really depends on the smell. Freezing might kill bacteria but it won't halt spoilage. So if it smelled bad enough that you felt concerned, we'd probably advise skipping it BUT if by smelling bad, you mean it smelled like raw poultry and you didn't want it in the fridge smelling like that then you should be totally fine.
