EIC or Dependent Care Credit Only

Son is 22 and wants to file and claim himself on his own return, he is on ours (married parents joint filing) not as a dependent as he is not eligible, but it says EIC or Dependent Care Credit Only once I punch in info.  Does this seem correct?  Can he file his own taxes now and claim himself for stimulus credit, however, we can still get him on our EIC credit (he won't get this on his own filing).
