Does line 15b on form 1040 correctly translate the correct amount of an ira qualified charitable distribution to the later explanation-page;

Amount of regular (not Roth) IRA QCD calculated by line 15a and 15b in form 1040 ($12500) was posted incorrectly on later "Explanation" page AND in my CO state form (as $10440), and likely also considered incorrectly in my MN state form.
