Professional Gambling income for Schedule C - no place to enter it so that TT treats it as gambling income and taxes at the proper rate

I am trying to figure out how to enter the income for my professional gambling activities.  I created a distinct business for this activity, and checked the box for "Is professional gambler", but the income is flowing to Schedule 1 as normal business income on line 3, not gambling income on line 8b, so it's being taxed at the progressive rate, not the flat 24% for gambling income.  

 

When entering the income, I don't see a way to specify the type, and I don't have W2-G's for it (online gaming sites).
