How do you access your profile in Turbo Tax? Support said: Support said I would find "view profile" on the navigation bar after sign in but no joy. diff browser no help

You can change your personal information in TurboTax by selecting your Intuit Account from the lower left side of your screen.  Here you can change all of your personal data (i.e. telephone number, email address, etc).  

Hope this helps!

Did not help.  Suggestion gets you to personal data, but not to place for editing credit card exp date.  Can anyone help with that?
