if youre saying your turkey has been in the fridge for a yr thawed?? TOSS IT!! if you meant your turkey was frozen for a yr then thawed I would be real careful. as a a rule turkeys thawed can last up to a week if kept in its original wrap and your fridge is cold, also....youll prob have to rinse it thoroughly and if it smells I would not chance it. depending on the size It only takes 3-5 days to thaw a turkey in the fridge. I myself would not cook it if left in the fridge more than a week.
