Are you referring to the email address used for the email verification code when efiling?
You can go to your settings in your Intuit Account, and you can change the email address. Here's how:
- In the left menu column scroll way down to Intuit Account.
- Then once in the account choose tab Sign In & Security.
- You can change the email address used for notifications. If you do, also try to go ahead and verify it while you are still in the account settings, then it may not ask you to again verify when you are efiling.
