I had same code, after 50 days I received a letter requesting proof that my kids lived with me even though my wife and I have been married in same address filing together same kids since birth. Sent the required info in it took them another 30 days to say they are reviewing it! I filed on feb 5 it’s now May 14th still waiting on refund .
Just received notice in mail they are reviewing and will notify us by 10/2018
Total crap
