Form 8615

The form is finally here!! YEA!! But i am confused  when I get to the page when it asks "would you like to calculate your tax based on pre-TCJA rules?" If I click no does that mean it will figure the tax on the new rule which is supposed to more favorable? When I do and continue a few pages later it comes to the page were it asks for "parents qualified dividends" and this amount should be on form 1040 line 9b of there 2019 tax return. Line 9 is for the standard deduction there is no line 9b the question also asks about capital gains. Could you please clarify which line of form 1040 I need to put in this field.
