Go back through the FILE section of your TurboTax interview. You'll need to select "E-file" when asked how you'd like to file your federal (and state) returns. Unless there is something in your return that prohibits e-filing, you should be able to select that option.
But you are correct....you can't use direct debit to pay your federal tax due unless you e-file your return. The TurboTax FAQ I'm linking below will explain further, and also give you another option to pay your federal taxes using Direct Pay.
What is direct debit and how does it work?
