While logged into your Online TurboTax, go to the left menu column and scroll way down to the tab Intuit Account.
In the account settings choose the tab "Sign in and Security."
Then you can update your email address that you want to use for notifications. You may be able to verify it there as well. If the new email address once entered has an "unverified" tag next to it. Click that tag to verify.
If you verify there, then hopefully it won't ask again during efiling. But if it does, then hopefully it will send the code to the updated email address.
Review the rest of your profile while in the account settings.
