No, when you registered for the Stimulus Payment through TurboTax, you gave the IRS your bank account information. You do not have to do anything else.
if no refund is due they don't send direct deposit information on 1040 to IRS. have to wait for IRS portal to add direct deposit information they are talking about.
I did this also, even got an accepted email back. still no deposit of my stimulus check, is the IRS not recognizing the turbo tax stimulus registration or not. I did this 4/10/20. The irs.gov, get my payment says no information available. Do they not have the information. do I need to re-input everything in the IRS portal?
