You can answer for any version of the Scarlet Witch, including animated, live-action and comic books. Just specify which version you’re answering for though.
Wanda would probably be a hufflepuff. She's really into yoga and tea and such. She's not avidly alturistic so she wouldn't be a griffindoor, or egotistic so probably not a slitherin, not very type A so she probably wouldn't be ravenclaw.
