The file date is listed as April 15th even though we filed it before then. It says on the transcript that’s the date they count from (which was annoying but made the sense with the timeline) The transcript is the best way to see where you are in the process because it gets updated any time someone opens the account to work on it. Hope this helps! We received our check in the mail 3 days after the transcript listed refund issued. It also included interest.
