Where do i find where to enter my bank information for direct deposit

At the very end of your TurboTax interview (under the FILE portion), you'll be asked how you'd like to receive your tax refund.  Once you choose "direct deposit", you'll be asked to enter your banking info (routing number and account number).

Is the direct deposit info entry before I file my federal return or after

@charleep You'll enter your direct deposit information BEFORE you e-file your return.
