The only way I know to make holes is to make the hole where you want and 'build' your wall around the hole.
Basically take the hollow circle shape and make it in the same 'plane' as your wall. Size accordingly.
Now here's the somewhat tricky part. Copy your hole and use the green shaded tool that's right in the middle of the 5, the one that looks like a square with an arrow pointing to the upper right.
Use that tool to resize your existing hole so there's some give around it. Don't size it up too much so that there's an open ring around your existing hole. This allows you to then build off of that hole and use your wall tool to then build around it.
I had to do something similar when trying to make a hole for the bottom of my sink build.
Again, that' s how I did it for my holes, but there may be others here who are more skilled at it than I am.
Good luck!
