I received a text stating 'CRITCIAL NOTICE' your turbo tax account is at risk, please log in - link provided. I'm assuming this is a scam. I logged into here - nothing.

Well if you pasted that link the word "customer" is spelled wrong.  

As soon as I hit "submit" to efile my taxes, I received the same text, and "customer" is actually spelled correctly.

(I assume the original poster had a typo)   When I log in, I don't see any security alerts either.:

This is the article you are directed to for that link (with customer spelled correctly): I received an email about using different TurboTax accounts
