I just tried to call PPS and most of day got a weird message that call did not go thru.  Now I got a call back and seemed weird and was told I could only inquire about business returns and not personal returns.  It seemed strange.  I am just checking to see if my return has been processed since I have a submission ID with date and my online account claims no return was filed.  I guess I will try again.....  866-860-4259 Is the number I called...
