California corporate tax underpayment penalty

This seems to happen every year for me. I've got all the numbers in my 2021 federal and California corporate taxes and I owe the minimum $800 BUT I am getting a $22 penalty for underpayment.

I paid the 2020 $800 taxes on time and made no other estimated payments. I plan to pay the 2021 $800 taxes in full before the due date.

Usually, find some special box to check or uncheck and this $22 penalty disappears. Can't find it in TurboTax for 2021. Would love some help. Many thanks!

I feel your pain, any luck on finding the answer?

The solution I found was to edit form 5806 and enter my extension payment amount in field 25 Amount paid by the installment due date.

Apparently TurboTax doesn't include the extension payment here.
