After you file

I was told that a letter was sent to me March 6th and then I was told that 2 letters were mailed to me feb 27th and March 6th and basically there is no refund set up for me right now because I am on a 45 day review. Well I did finally get my letter today and the letter was dated March 1st. Basically saying that my return is being further reviewed for accuracy. I honestly give up at this point. I don’t have a repo or eviction notice to show for a tax advocate but I am broke.
