TT calculates wrong federal tax given 2024 my taxable income

My marginal taxable income falls in 22% bracket.

In 2024 TT Home & Business, at "Federal Review" / "Let's Review Your numbers", my 2024 Taxable income is X. According to 2024 Fed tax bracket, it should generate Fed tax: 

     (Married joint-file)  23200*10% + 71100*12% + (X - 94300)*22% = Y

 

But in the review page, TT shows I owe:   Y + $3651

 

As another way to show TT is wrong, I bump one of my business' income, and only income, by 10K. TT shows my taxable income increased by $9293, fed tax owed increased by $3458.  E.g., I would be in the bracket of 37% while my total taxable income is less than 200K !!
