how ordinary business income is calulated

[qinhh]

I am using turbotax business 2024 for S-corp, I have a total service income $150000, salary paid $80000, Sep-IRA $20000, total deduction $10000, how the ordinary business income is computed? in the previous years, the business income of the corp is simply  

service income $150000 - Sep-IRA $20000 - total deduction $10000 - alary paid $80000 = $40000

Does this still how it should be, or anything changed? I saw a strange number automatically populated in a flush screen in the turbotax business 2025, qualified business income 

Any comments are welcome and appreciated

TurboTax Business will calculate your ordinary business income and display that total on Form 1120S Line 22. You can follow the calculations on this form.

Qualified Business Income (QBI) is shown on Statement A (under Schedule K-1 for each shareholder). Total QBI is usually 20% of ordinary business income. This may be the automatically calculated number you saw.
