Try these steps to recover your User ID or password:

Navigate to the account recovery page. Enter either your phone number (best option), your email address, or your User ID. Follow the on-screen instructions. Once you're finished, the TurboTax staff will either send you a code to help you recover your account, or show you a list of accounts associated with your data. If you remain unable to recover your account despite going through these steps, select "Try something else" on the Account Recovery page. You'll get extra security questions so that they can authenticate your identity.

Note: When you regain access to your account, you should add your current phone number if you haven't already. It's much easier to update or reset your account's security with a phone number.
