If you're referring to the email verification code some users need when efiling, see this:
- Log in if not already logged in, and low down in the left menu column choose Intuit Account.
- In your Account settings, go to Sign In & Security.
- Check the email address there, and update if necessary.
- If it has an adjacent tag that says "unverified" or "not verified", there may be a link to verify it there.
- If so, it will then send a verification email.
- Once you do all that, I'd log out of TurboTax, close the browser and reopen it.
- Then log in and try your filing again. It may or may not ask you again when efiling for an email verification code, but it at least it will be using your correct email address.
