****IF
YOU HAVE ALREADY E-FILED (and your Federal return was accepted), YOU WILL BE UNABLE TO CHANGE YOUR BANK
INFORMATION.
Unfortunately without the correct
routing number AND account number together (your check number is not a part of your account number), 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 and this notice will come
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
