If the return has an energy credit on it, that is your problem.  Folks have been posting that those returns have been hanging in limbo.

Yes they all have the energy credit on them.

Then that is the reason your returns are acting like they have a boat anchor dragging them down

Now I'm curious...... ALL of your returns have an energy credit ?     

Yes, I have the same issue and I am not able to get any help from customer support.  They don't seem to be aware of this.

3 different clients.

Yes I was on the phone with customer support for 1 hour and they couldn't tell me why they were hung up.

I don't know the real issue, but I can remember a couple of instances in prior years where there was an issue with a form and they held those returns for a bit until they fixed the issue.  When they got the issue fixed, the returns were rejected so that they could be re-transmitted with the corrected version of the form.  But like I said, I don't know if that is what is going on or if they have other issues mucking up the system.
