An enormous tax refund check is still burning a hole in a College Station man's wallet.

Michael Fredericks received an $18,000 refund, which is six times what he was supposed to get.

Fredericks says he knows it's a mistake and he's trying to return the money.

However, since the check was delivered Monday, Fredericks has tried calling the IRS to figure out how to give back the cash, but Uncle Sam has not answered.

Fredericks will continue his quest for answers. As soon as he finds out, we'll let you know what will happen to the money.
