As a college student and employee for 2018, would my son fill out a 1040EZ or 1040 form? Thank You.

My son is 18 years old and attending a university as a Freshman (2nd semester).  During his 1st semester in 2018 he worked a part-time job at the university and received financial aid in the form of Scholarships, Grants, and Loans.  As his father I will be claiming his as my dependent using TurboTax Deluxe.  Would my son fill out a 1040EZ or 1040 form?  Thank You.
