If you chose to have your refund direct deposited, the direct deposit information would be entered near the bottom of form 1040 near the signature line and would also be near the top of the filing instructions printed by TurboTax.
Did you efile your return or did you print and mail the return yourself? If efiled, was it accepted by the IRS?
