What didn't the IRS receive? You don't send a refund. You file a tax return form 1040. The IRS sends you the refund or you pay a tax due. Did the IRS mail you a letter? Or are you just looking at the IRS Where's my refund website? The refund lookup page doesn't always show your info and may not be up to date or accurate. Did you efile (and was it Accepted) or did you mail your return?
