Get your taxes done using TurboTax

The other option for your CA return is to enter nothing about your Bal Due payment on your return.

amount you owe would then be "Bal Due" + "additional due"

You only have to pay the "additional due" since you already paid "Bal Due".
You can pay the "additional due" to CA the same way you did it the first time.
