After you file

I have contacted them and it’s the same mess. They only show that they just mailed me one 4464c letter but I have received 9 of them. I keep on calling to see what is going on and every time they put me on hold then to come back and tell me to wait until the 60 days. If they need something from me then just say you need something from me I have nothing to hide. It just ticks me of that my refund was accepted and I got problems. Check a person that got errors on their refund.
