If you are not going to file a 2020 return you have no way through TurboTax to give new banking information to the IRS for a stimulus check if that is why you want to change it. TurboTax lets you enter bank information when you file a tax return. You cannot change it after you file. So if you entered direct deposit information using TT for a 2019 return, but will not be filing a 2020 return, you cannot change your bank information on the TT site. Wait and see if the IRS gives you a way to change bank information if Congress ever passes a second stimulus bill.
