After you file

Palex do you happen to know when the letter was sent out ? As of February 28th I still had no letter stated in the system that was mailed out to me according to the irs agent I spoke to. I have yet to receive a letter. I file January 27 and my refund was excepted January 28 and I received the delay message February 15 and it went back to excepted and processing March 1 but according to the IRS agent that I’ve spoke with in February I was in a 45 day review that was supposed to start March 4 so I’m so confuseD
