Employment Information Section on Apply Texas Application

So the heading states that the section is for “Employment, Internships, Summer Activities”

I’ve never had paid employment here in the United States. During most summers, however, I worked in the family business abroad, without an official paycheck. Additionally I’ve done unpaid volunteer work at a local hospital. Should I include these under this section? This is coupled with other things like Band Camp, are these things I should include in this section or would they not be appropriate.

My basis would be the “Summer Activities” part of the title.

This is for UT Austin auto-admit if it matters.

Thanks!
