I am trying to find out if this plant is toxic to animals, particularly turtles. I have a member of my group that is feeding this to her red-eared slider and a box turtle. I want to make sure it cannot harm either animal. It is not on my lists of toxic plants.

While Syngonium podophyllum is listed as toxic to humans, that doesn't mean it is toxic to turtles. You would have to ask a turtle expert to find out for sure.
A friend of mine cannot keep a syngonium plant indoors becasue her cat eats it. No harm to the cat. I have two syngonium plants, both go outdoors in summer. A deer came into the yard, ate all the leaves off of both plants (and ate the sedum too!). The deer is fine, as far as I know. I doubt syngonium will harm a turtle.
