Answer
This is probably a fungal growth. Pretty common but annoying.

First of all, check over your basic cares- water temps, lighting, filtration, etc. You can use a site like http://www.redearslider.com as a basis for the review.

Once the basic cares are rock solid, you can treat the growths by gently scrubbing the turtle with salt and a soft brush. If it keeps coming back, try using the fish medicine Stress Coat.
