Conservation Easement Deduction 100%?

I am a full time farmer and I had a large non-cash charitable contribution in the form of a Conservation Easement on my farm property. Turbotax is only giving me 50% deduction of my AGI. With most of my income from farming, I am supposed to get a 100% deduction of AGI. How do I get Turbotax to recognize this. There are no boxes or choices in any of the menus.

thanks
