Once a return has been accepted by the IRS you cannot change how you want to receive your refund.
Thank you for your prompt reply. Maybe you can help me a little further. I am fine with my refund being direct deposited. But I don't want my coronavirus stimulus "check" to be direct deposited. I read the IRS is paying the stimulus check according to tax return info. That is why I wanted to change from direct deposit to Turbo Visa card. Can I amend payment to card just for stimulus payment?
