how do i change my email for my return

[JamesG1]

Your email within your Intuit account may be changed by selecting Tax Home in the upper left hand corner of the screen.  

Then select the down arrow to the right of My account towards the bottom of the screen.  

Then select Change user ID, e-mail, or password.

Or, are you referring to an email address within a state income tax form?  Which state?  Please clarify.
