I talked to a woman at the IRS today because my status was stuck on "Still being processed" she checked on my return and there was a slight error. When this happens and the IRS can fix the error without needing any further information from the taxpayer they fix it. It's usually something very minor that doesn't affect the refund amount. However, it does make your return go back to the beginning of the process. It can take 8 weeks for the return to be approved when this happens. But with early filers the delay is usually only a couple weeks.
I feel relieved with this information. If a return is pulled for review or they need additional information you will know within 2 weeks either by letter or by "Where's My Refund?"
