CA Form 5805 Line 5 is incorrectly using 2024 tax amount (from Line 2) instead of imported 2023 amount.

Well this seems buggy... Turbotax Premier (Mac desktop) said I owe a penalty for underpayment of CA estimated taxes.  A bit surprised, I checked Form 5805.

Why is Line 5 using the amount from 5805 Line 2 (the 2024 tax amount)?  It's supposed to be using the 2023 tax amount which I see does show up correctly on the California Carryover Worksheet Line 2.  This issue is causing incorrect underpayment calculation on 5805 Wks II.

I have the latest updates installed.  I've tried creating a new tax return and the issue still occurs.  Please help!

Correction: It's not causing incorrect underpayment calculation on 5805 Wks II.  I do owe underpayment penalty due to my circumstances.  The value shown in Line 5 still seems incorrect but doesn't make a difference in the calculation.
