In most cases, TurboTax prepares the necessary forms and gives you the option to provide payment for any taxes that are due.
If this is for a Single Member LLC, be sure you answer Yes for SMLLC under California Schedule C so that TurboTax will prepare Form 568. There is a similar question for Schedule E.
If your company has more than one owner/member, you will need to file the return using TurboTax Business.
If you need to file a different form, please clarify your question.
