After you file

Just received my refund yesterday in my account with interest; hopefully you guys will get money soon too.

 

I recommend calling early (before 10 AM).  I was able to get someone most of the of the time I called.  It was about an hour wait.  Processing centers are opening so they may now be able to tell you the issue (last time I called they were able to tell me the issue and that they also resolved it).
