I recently removed a tree, ground out the tree stump, and patched the
area with sod.

It appears that I put too much dirt in and now there is a slight hump
in this area. However, I am trying to determine if there was already
a "hump" there, due to the tree.

When trees are planted, is the soil around the tree trunk usually
graded towards the tree trunk?

I guess what I am trying to figure out if it is worthwhile to remove
the recently installed sod, and properly level the soil and
re-sod...I'm not sure if the hump is already there in the existing
soil.

Any advise would be appreciated.
