Refund Returned

I E-Filed my federal return and according to tracking my refund was submitted on 2/14.  I have daily checked my account to see if deposited.  Went to the bank today and learned they returned the check because I had inadvertently added 2 extra digits to the account number (which I had meant for the savings account).  I had already checked savings on the form but since it was "not" part of the official account number the bank refused it.  What do I do now?  Amend the return to correct that or ???
