Just my two cents, but, in e-filing we call these "Error Acknolwedgments." The e-filing FAQ puts it simply and best: Verify that the CTR filed matches the BANK'S RECORDS. If it does, take no action. I discourage people from telling customers what forms the customer has to file with the federal government, and from wasting the FI's on-the-clock time tracking and pursuing these non-issues. A tiny fine might apply if you file interest forms on her to the IRS, but if she is in a non-interest bearing account, who cares what the SSA has on file?
