I have no idea why you'd receive such a email from TurboTax. Be sure that you don't reply or click on a link in that email.
Here's what I'd recommend:
Log into your TurboTax account and verify the accuracy of all the information you have there. Once you're certain that everything is correct, you should be good. The TurboTax FAQ I'm linking below contains instructions on verifying your TurboTax account info.
How do I update my TurboTax account information?
