I filed early as well on the 17th of January, I received these codes on my transcript 570/0.00 and 971/0.00 different dates and according to my research. The 570 was because of the path act that didn't go into effect until the 17th or 18th which in turn puts a hold because I passed the initial time frame of 21 days. I also received code 971 with these combined codes it means I passed the initial process and just waiting on a refund release date hopefully this helps. Just check your transcript.
