How to Add Line Breaks to part of the Donation Object's 'Short Description'

Site URL: https://www.jerredandnatalie.com/equinox-gathering

As seen on the included screenshot. That is the "Short Description" part of the Donation Object.

Is there markup so that I can format that area? I tried, "<br>" But that isn't it.

Thank you.
