You can also request your code via text message. To receive your code through text please complete the following:
1. Sign into your account
2. Select My Account
3. Select Account Settings
4. Select the blue Security tab on the left
5. Select Two Step Verification
6. Select Turn On
7. Enter your Phone Number and Password
8. Sign out of TurboTax, close your browser and sign back in. You should receive a verification code shortly after signing back into your account.
If you are still unable to get the code to work through text, choose I forgot my user ID or password and then choose I don't know my email address or user ID. You’ll be asked to provide some information about yourself, and then you’ll be asked a few questions verify your identity. If that method fails, you’ll get a phone number to contact customer support.
