How do I change my phone number for alternate account recovery?
To change your phone number, log in to TurboTax Online, open a return and then select "Account Settings" from the bottom of the black left side menu. This will open another page for the Intuit Account Manager. There select "Sign In & Security", then click on "Phone" and you will be able to change your phone number.
