For the Pathfinder 2e by Roll20 sheet: Click Options next to Alchemy. Then at the bottom right there is the NPC and Kingdom switches. For the DnD 5e by Roll20 sheet: Click the settings icon next to Spells. Then on the top right corner there is a drop down menu for PC, NPC, Kingdom, and Vehicles. I don't know where the switch is for the Pathfinder by Roll20 sheet. I could check though if you are using that sheet.
