Avatar overly large and viewpoint not set in the correct place-

I’m new to creating avatars and have never had to deal with this before. Wondering how I fix this sizing issue (for clarity, the avatar is only meant to be up to waist height compared to a regular human avatar) but is excessively large. I’m also finding the camera viewpoint is set lower than I originally set it (which is at the head.) I think the camera point may be related to the size but I don’t know. Any help?
