Retirement tax questions

I am in the process of preparing my 2023 tax return and came upon this chain of messages.  I likewise have an issue with line 18.  Based on my situation I know that I must use the worksheet to calculate the amount for line 18.  I have been using Turbotax (desktop version) for many years and every year I prepare the worksheet and manually override the amount on line 18.  In my situation the rational for needing to complete the worksheet is very straightforward.  I would think that Turbotax could use the same logic and automatically make the necessary calculations so that the amount on line 18 is correct.
