You can change this as long as you've not filed yet.
If you have not yet filed your return, to update you
bank account information, sign back into your account and click on the
"File" tab. Continue until you get to the screen asking how you would
like your refund, once on this screen select "paper check", and continue.
Once you have filed, you cannot change this; you will ultimately
get a paper check. What will happen is basically the IRS will try to deposit
the refund into the account on record. Since the information is not
exactly correct, the bank will reject it and send the refund back to the
IRS. Once the IRS gets your refund back they will issue you a paper
check and send it to the address that you put on your return. You can
