Does anyone know where to access the Qualified Business Income Deduction in the Home and Business desktop software?

Hi. 

I have spent about an hour scouring all the tabs in the business section of the Home and Business version of Turbo Tax to try to find where I can access the Qualified Business Income Deduction. And am unable to find it. Does anyone know which section this is under in the desktop software? The only answer I can find on the internet says Screen 18 which isn't helpful. 

TIA
