In order to import, you must use the same user ID and password for both your Mint and TurboTax accounts.
If you already have a TurboTax account but with a different user ID and password, you won't be able to use the import feature at this time. However, you can still import tax documents directly from your financial institutions.
Please see the TurboTax Article below for more information:
How do Mint and TurboTax work together when importing?
