I filed before midnight April 15 but status still shows pending. Will I be penalized if it doesn't go through before midnight?

No---you filed on time even if it is in pending for now.  Watch your emails.

When you e-file your federal return you will receive two emails from TurboTax.  The first one will say that your return was submitted.  The second email will tell you if your federal return was accepted or rejected.  If you e-filed a state return, there will be a third email to tell you if the state accepted or rejected your state return.
