Ive never seen the message "awaiting acknowledgement" anywhere before.  

Are you really using ProSeries Professional like your post shows? or some other tax program?  If so, try highlighting the file in the EFCenter and then use Update Acks of Selected Returns, see if that will pull the ack in.

I assume you've checked "received acknowledgements statuses"? Have you efiled others after that one that have been accepted?

@Mearl313  you started a different thread on this, I posted on it to come back to this thread, it gets too confusing when there are multiple posts tangled up together.

Did you try what I showed above?
