@camie22e how long did it take for your 9001 ref to go away?
I filed 1/28/19 excepted 1/29/19 and got message we can not give you any information about your taxes for 2 days. On the 30th i got the 9001 ref code and it lasted until 2/3/19 and now I'm on the Path Act message
Path Act usually causes this. The amount will reappear when it is processed and approved with DDD later in the month.
