Still haven't received my refund. Filed on the 15th and at the 21 day mark my status bars disappeared and turned to topic 152. Does anyone know why? I did file with the EIC.

Although most refunds are processed within 21 days of acceptance, some returns require additional review which causes a delay in processing. Please see Why do some refunds take longer than others? for more information. 

If it has been over 21 days since your tax return has been accepted, please see What if my IRS refund is taking longer than 21 days?
