Do you mean paying the actual taxes due on your return?  You can pay by credit card on the CA FTB website.  Please click this link:  Payment Options

If you do make the payment on the CA FTB website, please remember to enter that payment into TurboTax BEFORE YOU FILE so that you get credit for it on your return.

To report the tax payment you made, please follow these steps:

1. Click on Federal >  Deductions & Credits. 
2. In the Estimates and Other Taxes Paid section, click on the Start/Update box next to Estimated Tax Payments. 
3. On the next screen, Did you pay state estimated taxes for 2019? click the Yes box.
4. Enter your payment(s) on the next screen, How much did you pay in federal [or state or local] estimated taxes? Select the state from the drop-down list and enter the amount paid in the box.
5. If you made more than four payments, click Add another payment at the bottom of the screen to add another line.
