Invalid E-mail

[Elawen]

The e-mail I have used for filing my taxes, as well as the one to log into my account, now says it is Invalid and I can not submit my tax return. According to the write up on the page of what a valid e-mail address is, it is valid. How do I fix this?

You can click on the "Try Something Else" option on the bottom of the sign in page to see if you can get in that way. If that doesn't work, then you can use this form to submit a TurboTax Account Recovery Request:

That has nothing to do with my question, I can log into and access my account just fine.
