After you file

I also got accepted the 22 of Jan and have stayed in processing with nothing else. I had a 3/2 processing date. But I also had a code of 570 and 971. I called the IRS today and they told me that i should receive a letter by the 9th because I am in a random review. She did say that it would not take that long (60 days) and that I wouldnt need to do anything but that the review didn't start until I received the letter. I have seen others with the same review receive their refunds even before the letter arrives so Im not really sure that the review isn't already happening. I guess its a waiting game. An absolutely ridiculous one.
