I had the exact same thing happen yesterday. I was accepted on 1/31/18 and never got any updates, turbo tax still says my expected date was 2/21/18. Yea, that didn't happen. I called yesterday morning the same number you called only to be talked down to by a rude representative and still had to call back a 2nd time which was much better to be told that my return was selected for a random review for no known reason and that it could take until April 1st before I see my refund. She said that it is not a definite that I will have to wait until 4/1/18 but thats when the 45 days would be up. Its all a bunch of bull if you ask me. I filed with TT last year and had the same thing happen and my return is very straight forward too.
