i have the same situation as y’all! was accepted the 29th, got my state a week later, still no federal. called and was told im on a 45-60 day review and was sent a letter the 23rd. called again today spoke to different agent and he said he has no idea why i was told i was sent a letter because there is nothing in my case of being sent a letter or intent to send a letter & that my case was pulled for review February 15th which is when my 45 day count starts and if i dont have my refund before March 31st ro call them. He said it could be tomorrow that I get it or next week or even March 31st. He said its not necessarily the whole 45 days, it just all depends when they finish with my case. The 45 days is just a time frame. So frustrating i really hope i get it sooner than the 45 days!
