Be careful. There are a lot of phishing emails trying to infect your computer to steal sensitive info. So do not click on any links, and do not download any attachments.
Who was the email allegedly from? Was it supposedly from TurboTax/Intuit? Even if looks real, it can be fake.
You can report a copy of the email with intact headers to https://security.intuit.com/ , and they will evaluate it.
You can phone TurboTax Support if you need help.
