I had one of these audits last year when my tax guy claimed a tuition tax break (graduated this time :) which I had already fully utilized during my younger years before dropping out. The IRS sent a letter saying "you already claimed this credit" and I marked a form indicating I was no longer claiming the credit and sent it back. The entire process put my refund on hold, but once cleared up I still got a refund.
