How do i report income on ESPP stock donated to charity (the discounted portion)? Where would I report it on my return? What form? Income or deductions?

I donated ESPP stock to my church.  I need to report the 15% discount on the FMV at the time of purchase as ordinary income.  I need to know where and how to report that in my return.  Would I report it in the investment sale area?  Dividend and Interest Income?  Some sort of other compensation?  Maybe in the area where I entered my W-2?  Or, would I report it somehow in my deductions?
