So yeah it’s been 7mo this since I’ve filed. I received a 4800c letter it didn’t ask for additional information. Just said they proposing changes to my return. I have a regular and simple job. Not in school no kids not a homeowner etc. how long does it usually take after you agree with the changes they made on my return. On the 4800c letter it said to mail in or fax a part of the letter that’s I signed if I agreed to the changes. I did that August 1. Which was also when I received the letter.
