Mine was under review as well. I filed on 2/8/18 and was accepted the same day. I called on 3/2/18 to find why I hadn't received my refund yet, they told me I was on a 45 day hold for review and should see my refund by the 1st or 2nd week in april. Called again on 3/8/18 and was told still under review, expiring on 4/7/18. Then yesterday, I logged in to see if there were any updates on what I would need to do, and it said I was approved and my refund date is 3/14/18.
