QCD

I am using TT Deluxe 2024.  I have gone through the entire data entry with significant QCD donations entered.  When I get to the taxable income/tax due, ALL of my income is shown as taxable (and that includes the QCD amount).  I keep getting the message that standard deduction gives us the lowest taxes.  But the QCD's should reduce my taxable income before (and therefore separate from) my (our) standard deduction.

What's the deal.  Why is all of my income showing as taxable?
