Pending status for over 96 hrs. Problem with TT or IRS?

Both federal and states were filed on 3/24. According to TurboTax efile status, it's still pending on 3/28.

 

Is there a backlog problem with IRS?  I never experienced such long delay. Usually got accepted within a day.

 

Got a feeling that my returns got caught in a black-hole.  ðŸ™‚

 

Anyone seeing similar delay?

 

Thanks!
