Shading/mesh Error. How do I fix this?

So I connected some polygons together with the fill option, so how do I fix this ugly shading error?

I run into this problem ALL OF THE TIME. How can I fix this? This object is perfectly round and shouldn’t be shaded like that in the middle.

You have some normals facing the wrong way. Recalculate normals to fix. Edit mode, select all, ctrl-N.

Ah, thank you so much! No more sloppy edges! Thanks x10000
