On my college application, am I supposed to give my GPA for my senior year only or my total GPA?

On my college application: What was your unweighted high school GPA (grade point average)? Please enter a value between 0.00 and 4.00. If you are still in high school, enter your cumulative unweighted GPA as of the end of 11th grade.

total GPA

It does not say anything about senior year only.

Although, it occurs to me that my high school only reported my senior year's GPA.

That's what HS counselors are for. Talk to yours.
And if your counselor can't help, see your school's registrar.
