Qualified Business Income Deduction

I'm having trouble finding out how to get line 9 filled on the 1040 (QBI). I was able to manually enter it when I used Premier 2018 but I don't remember how I did it exactly. 

 

Can someone please help me figure this out? I cannot seem to do it manually in the forms option and I cannot find it anywhere in the step-by-step option either.

 

I have 2019 Home & Business download version.  

 

Thanks.
