****IF YOU HAVE ALREADY E-FILED, YOU WILL BE UNABLE TO CHANGE YOUR BANK INFORMATION.
Unfortunately,
without the correct routing number AND account number together, your refund
will not come via direct deposit. However,
don't worry! You
should receive notice from the IRS when they cannot complete the direct deposit
via US Mail. This notice will let you know that a paper check should
arrive shortly. Please see the following link for more info on the IRS notice
you will receive: https://www.irs.gov/individuals/understanding-your-cp53a-notice
