How do i make my terrain able to use tangent geometry

I'm using unity 2019.2.3f1 i'm trying to apply ground texture to my terrain so i can start making the land and add tree and rocks, every time i put my material tho any of them , I get that message "Can't Use Materials With Shaders Which Need Tangent Geometry on Terrain, Use Shaders In Nature/Terrain instead" even making a new material from scratch same thing. I know i'm missing something since i'm new to this but i can't continue until this problem is fixed i've search around and i have found no answers, i've seen people ask the same question with no resolution. if anyone knows to to fix this problem it would be extremely helpful.
