summer internship tax question

My son is a college student in Illinois who worked as an intern in the summer of 2024 in Connecticut. He had an apartment with friends in New York City and commuted to his internship in Connecticut. His residence/drivers license is still Colorado. Where does he need to file state income tax returns for 2024? Does it make a difference if his parents still claim him as a dependent on their tax returns?
