Since you already filed your return, you will need to wait until you get the status of your return (accepted or rejected).
If your return gets accepted, you would need to amend your return to make changes. Amended returns must be mailed and it can take 8 to 16 weeks to be processed. There is no direct deposit on an amended return. TurboTax amended return will not be available until sometime in mid-February.
