Get your taxes done using TurboTax

Not sure this helps but I found this

To get a list of your User ID's and recover accounts, you can use the tool at the link below.  If you have more than 1 email address, you should run the tool on each one. 

NOTE: Before running the tool, log out of all Intuit accounts including this user forum, or you could end up in a loop.  Then clear your browser Internet cache, close your browser, then reopen it, and go to:
