I'd like to change the type of room, I posted a listing as a private room but it is a studio

Go to Manage Listings > Calendar and More > Click tab with four parallel lines in upper left corner > Basics > Scroll down to Listing Property Type > Select the correct option

Unfortunately I don't think they have a Studio option. If your space is an entirely private space with kitchen, bath, bedrooms, etc then you can select Apartment.
