This is a user community forum, so we don't know who sent you the check or anything account-specific, and we don't know if it is for 2024 or a prior year. And we also don't know if it is an income tax refund (Federal or state) or a product refund. You didn't mention who sent you the email, such as if it was from Intuit/TurboTax or from a third-party company SBTPG, who is involved when TurboTax fees are paid out of the Federal refund.
In short, this can't be resolved in this forum. The first thing I'd try to find out is why there is a check in the first place and why was it using an old address. Here's how to phone the folks at TurboTax Support.
