Get your taxes done using TurboTax

I also received a letter (in the mail, not e-mail) like the following:

"Dear Valued Turbotax customer,

We recently sent you an email with the subject line "CRITICAL NOTICE: Regarding your 2020 TurboTax Return." To ensure that you received the communication, we are following up with the same message by mail.

Because of an error in a Turbo Tax calculation, you have overpaid the income tax on your 2020 Federal tax return. 

..."

Is this e-mail legit? If not, how did the mailer know what software I used to file my tax? how did the mailer know which form did I file?

 

Can anyone please reply my question? I tried to look for an online chat support to verify this in real time. But couldn't find one. Thank you very much!
