Received the same letter. Was told to wait, and wait, and wait. Finally got tired of waiting and tried several times to reach a live agent. Finally got a resolution after calling the automated questionable credits department, [phone number removed] hours are monday-fridsy 7am-9pm central. They were able to sdvide me why it was being held and how and where to submit the required documents. My employer misreported my wages, and did not send a correction until after I filed. Now waiting on the review of uploaded proof so I can get my refund released. Hope this helps anyone still in limbo.
