Turbotax 2023 -- does not appear to consider solo 401(k) Employer Matching (Profit Sharing) Contribution in tax calculation

I took the "standard" maximum $22.5K + $7.5k deduction on Schedule 1, Line 16 for my solo 401(k). The program shows certain owe/refund amounts for Federal and State in the upper left. If I increase this amount to the Contribution Worksheet max to include Employer Matching (Profit Sharing) Contribution (let's say it's another $15k), the program doesn't change the owe/refund amount.

It would seem the owe/refund amounts must change if the employer contribution is before taxes. Otherwise, I'd be paying taxes twice on the employer-contribution amount, now and then down the road when I take RMDs on the solo 401(k). It is my understanding that all funds in 401(k) accounts are pre-tax.

It appears (?) that the program wasn't recalculating. I went to forms and hit 1040, Schedule 1 and supporting worksheets and the owe/refund number changed. So I withdraw the question.
