The IRS may be working on a backlog of returns at this time, so it can sometimes take longer than the initial 24-48 hours before you know if they have accepted or rejected your return. This generally happens around this time when e-filing first opens with them. And the state will remain pending until the IRS accepts your federal return.
As long as it's pending, you know that it's still on the way to them. But you will get an email when your return goes from pending status to Accepted or Rejected.
Also, once you've been accepted, wait at least 24 hours before you use the IRS Where's My Refund? site. If you jump the gun, you may be told – incorrectly – that you never filed. And state can be tracked by going here How do I track my state refund?
