How do I enter minister's housing allowance

I have a letter from my church recording my Housing allowance which is 100% of my compensation ($2200) How do I enter it since - as it is not my business income? Mileage: I often must drive to the church for police activity, trash removal, plumbing etc.  that is not my ministerial duties-is that deductible as a business mileage expense?  I also use my device to do live streaming each Sunday-does that change the mileage deduction status? Please forgive all of the questions. I am trying to give you content for my questions thank you.
