After you file

So I got it cashed and literally the next day I got a call fro, the place that cashed it and they said my turbotax check was a fraudulent check!!!!!! So turbotax where is my money especially if you guys said that was supposed to be my check on the phone when I cashed it and my turbotax refund tracker says i recieved a check by mail and that's the only one i recieved.
