Hello
The best and the most accurate way to track your refund in my view is to go online at its.gov and view your Account Transcript. That's what I did all the information on there will tell you if your refund was issued (code 846) or if there is a problem( other error codes) and your DDD. It also shows if you have a credit to your account. If you see your refund amount at the top of your account transcript with a minus sign in front of it that means that it has been credited to your account. Most likely with that you should be receiving a refund soon.
Hang to you guys they have updates coming on Saturday
Good luck
