Every time I simulate a fluid simulation in blender it always 'hovers' above the desired collision. I've tried applying the scale, I've also tried to set the normals to a smaller size but still no changes. I'm not sure what could be causing this.

This little box which you can see in your domain represents the "smallest unit" of your fluid. If it is too big, it cannot "see"/recognize your obstacle. So you could either increase your domain resolution and/or increase the thickness of your obstacle.
to make it work change this:
select your plane (obstacle), add a solidify modifier like this:
Note: It has to be before your fluid modifier.
Uncheck your "is planar"
bake again and you will get:
or...without the modifier:
uncheck "is planar" and change resolution to 120:
