I uploaded supporting documents to the IRS using the Document Upload Tool (DUT) five days ago. So, today I thought I would call to confirm that the documents were received, and see if additional information may be needed. I was transferred to the Accounts Management Dept. Their reply was "check again after 60 days". They say it takes that long for posted documents to become available to them. That sounds very inefficient. Has anyone had experience using the DUT?
