My new daughter-in-law, (who married my son in Nov 2020) finished graduate school in June 2020 at the age of 24. She did not receive either of the two 2020 stimulus checks. But she did receive $600 from her school as part of the Emergency Student Support Grant through the CARES act. Is she allowed to claim the entire $1800 for the stimulus checks? Or is she only allowed $1200?
