Deductions & credits

I seem to be seeing a similar issue in TT 2024 - No or minimal tax due in Q1-Q3 but Q4 seems correct.  In my case, I had a large Roth conversion that hit in 4Q that doubled my income. That said, even without the Roth I would have expected there to have been tax due based upon the annualization factors.  What was the final resolution of this and is it still present in the 2024 version?
