Qualifying Child or Dependent

Hoping to just clarity on this question. 

 

My child is 25. He did an internship out of state for 6 months of last year while attending graduate school. When the internship was over he stayed in the state he did the internship to complete his graduate degree. Can I claim him?

1- He was in graduate school for 8 months last year; tuition paid by 529 withdrawals; 

2-For 6 months of that time we assisted with rent;

3-He did make more than 20,000 last year

 

Turbotax says he cannot be claimed because he made too much income and must file his own return. Just want to make sure that is correct. Thanks
