MonikaK1,
The genesis of this thread was that TurboTax is not carrying the 2023 CA state liability correctly onto the 5805 at Part II line 5. If this were fixed - and I'm pretty sure it worked in prior years - then much of the question/confusion at this point would never occur because TT would correctly calculate no penalty. Does TT have any plans to fix that issue?
Personally I always pay in enough to avoid the penalty and the only times I've seen the form come up in the past are when I needed to use the annualization method due to some odd transaction late in the year bumping my taxes. Even if my tax liability increased significantly year-to-year I've never had to deal with this before as (presumably) TT did fill in that 5805 slot correctly so the form never showed up, just sat on the sidebar (I use direct entry rather than interview).
