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.
