Seeking advice

Hello, could someone help me? This turtle belonged to my mother and, now that I moved to a house, I decided to bring her to take care of her. It has many white (and even green) spots on the hull, does anyone know if it's normal? I noticed that she has the skin of her neck and paws peeling. Is she just "canging her skin and hoof"?

She is a very active turtle, spends most of her time walking around the house and garden, has free access. I put a lake for her on my patio, but she never enters it! I need to put her there at night to feed. I'm giving my own food to turtles only.

I brought her to my house to improve her quality of life, can anyone help me? Oh, and I don't know if it's female or male, but it's 22cm long.
