18yo left home and got financial aide

My wife and I had legal guardianship of our nephew. He turned 18 in April, ending our guardianship, but he continued to live with us until mid-July. When he moved out, he moved back in with his mother (my wife’s sister). He started junior college and signed up for and began receiving federal financial aide.

 

My wife and I plan to claim him as a dependent on our taxes as he lived with us for more than half the year. Does his receiving financial aide after he moved out affect our taxes in any way?
