My federal taxes were accepted last week bu my CA state taxes still show pending? Did I do something wrong?

No, you did nothing wrong. A pending state return is not unusual. Your state will show that way until your federal return has been accepted by the IRS (not accepted by TurboTax). It can only be e-filed once federal is accepted. 

federal tax was accepted, and california is still showing pending. does anyone know why?

Even if you filed your federal and state returns at the same time, your state may not start processing it at the same time as the IRS.

It's not unusual for state returns to remain in pending status several days after a federal return has been accepted. This is especially common when e-filing first opens in January or early February.

Sit tight and your state return will (eventually) move along in the queue.
