If I file an extension for my taxes, how can I estimate my California income taxes owed?

I filed a federal extension to my taxes, and I understand you are given an automatic extension for California state taxes but need to pay whatever you owe currently. I have a 1099-NEC of around $2100, how can I figure out how much I roughly owe California?

If that is the only income you have you will not only not owe any tax, you will not have to file either a federal or CA tax return.  The minimum for both is $12,550 which is the standard deduction
