After you file

I received a message on February 26 telling my my return was accepted and pending.  As of today , April 4, it is still Pending Is there any way I can find out why it is not making any progress?  I'm getting concerned.  So far I have not been able to contact anyone at TurboTax of the IRS.  Keep getting the run around on the phone, ending up with the same information that it is "Pending."  Is anyone else having this problem.
