I went under review in 2018 for my 2017 tax return. I turned all the required documents in and waited. Every couple of months I would get a letter explaining that they needed 60 more days. This went on for a year and a half. I never got a notice it was handled but I did have it ruled in my favor and received a refund check in the mail with a small 300.00 interest for the 18 month wait. Sadly I'm under review again this year. Hope you don't have to wait as long as I did.
