Yes, there is something you need to do.  You need to determine why your California return was rejected, correct it, and re-submit.  If you are unable to successfully transmit  your state return, you will have print and mail your state tax return.  If you don't e-file your state return, or mail it, you won't receive any refund you are due, and if you owe, you could be subject to penalty and interest if you don't file by the due date.  For information on fixing a rejected return, see the following TurboTax Help Article:

How do I fix a rejected return?

The email that I received from Intuit when my California tax return was rejected included the following:

"

I followed the instructions (which involved checking certain portions of the federal return), then recalculated and resubmitted the state return (at no additional charge). 

Let's see what happens. 

Same here. Filed both on Jan 29th. Fed was ok. But checked today and state tax said pending on Turbo tax, Californis Tax Board site said had no record, even after giving them a submission verification number given to me from turbotax assistant.  They said to contact turbotax again. And then today Feb 18th got an email from Franchise Tax Board stating it was rejected. Went back into Turbotax also shows rejected, and saying "it happens sometimes. Let's fix it" So it takes me back into Turbo Tax and says nothing was wrong with my return, but there was an error in the Turbotax software that caused it to be rejected. All I had to I had complete a small form that wasnt there before. So I did that , and resubmitted it again. We will see what happens next. Anyway, evidently people who filed through TurboTax early, got rejected, because of their of an error in Turbo Tax softwware. Maybe this is why your state tax  says pending or rejected. Hope this helps.

I never got any instruction from turbo tax about how to proceed.   I ended up correcting it, printing it and paying $25 to mail it from Korea.  I want a refund for the software, which was inaccurate,  and the filing fee, because electronic filing didn't go through.   TurboTax never responded to my rquests for help.
