If you have not yet filed
If you transferred in information from your 2015 tax return, you may be shown the same bank information that was used last year to have your refund direct deposited.
If you have already e-filed or paper filed
Once your return is e-filed and accepted then no changes can be made to the return, or your refund payment method. If it is rejected, then you can go back in and modify the refund payment method.
If the IRS tries to deposit your refund to the bank account on the return and it is closed, or the account name does not match the return name, it will be pulled back and automatically sent as a paper check to the address on the file as the mailing address on the return.
This is a Turbo Tax FAQ with a video that explains this process.
