TurboTax has several phone numbers. Because that is a security issue, if the email is legit, it may be a direct phone number to TurboTax/Intuit Security. If general TurboTax Support acts like they are unfamiliar with the contents of that letter or the phone number in it, ask to speak directly to the Security Dept.
I found an old thread. Is the number shown in this previous thread the one you were provided in the email?

If so, read that whole thread, including the answer by @Opus 17
I've also tagged him, so he may also comment here during the day today.
