<prompt> Human: I redid my wifes taxes for 2010 and 2009 because she didnt claim education credits when she should have. The amount that she recieved was more than we expected. The bottom of the check noted 80.44 interest, and indeed the amount of the check is 80.44 plus the amount she was due. Is this legit?  <response>: If you got an official statement from the IRS and it clearly labels the interest paid, why would you doubt it?But yes, its legit and thats standard policy.
