Interesting -- I actually had to delete "5805 Wks II" to get things to look right. While the worksheet still lists the payment due dates as 4/15/2020 and 6/15/2020 for (a) and (b) respectively (when they should both be 7/15/2020 as can be seen on the actual worksheet on the FTB site), the penalty is now correctly eliminated.
Very annoying though that the automatic software and form updates didn't fix this, Manual intervention should have been unnecessary.
Thanks for your feedback.
