Is 2021 Form 8615 calculating correctly?

[SoDak]

I have a child who's required to file Form 8615.  The parents used Schedule J to figure their tax liability on their return.  I believe the child should owe tax on his unearned qual div/capital gain income based on the parents qual div/capital gain tax rate of 15% when using the Schedule J.  Form 8615 in ProSeries is saying the parents' income tax on line 9 is $0 with the Schedule J box checked.  This is a calculated field.  If I override to show the parents' tax liability will the child's return reject.  I have the Schedule J worksheet filled in that goes along with Form 8615, but the correct numbers are not flowing to the Form 8615.  Am I missing something?
