How do you file a California extension on this website. I was able to do a federal extension but so far cannot figure out how to file one for California California

No need to do it. It is automatic for 6 months:

This is not an extension to pay. You can pay online at:

Good luck!

Thanks for the answer & link. It would have been much more comforting had the answer come from a TurboTax expert.
