After you file

That's not uncommon this time of year, the backlog of paper filed forms (mostly people that filed their original too soon and forgot to include certain items so they had to amend) can be overwhelming for the human processing staff.   Its generally best to put some form of tracking on the envelope so you at least know it made it there, I had an amended return a couple years ago that took over 2 months to show up as being recevied
