Removed sections of my garage floor to lay in thicker pads for some supporting posts. Obviously, when I cut the floor, I overcut the corners, leaving 1/4″ cuts about 4″ long on all four corners.
I’m planning on putting in an epoxy finish on the floor when it’s smooth, so what’s the appropriate material to fill these saw kerfs?
Thanks.

If I understand your problem correctly, the cuts are in the concrete at the corners where you added the new foor?
Suggest getting a can of "Instant Concrete"(not a brand name) in a quart size container at one of the big box stores. It comes premixed usually and should fill in the saw cuts using a small spatula. This product is similar to filling joints or holes in drywall except it is for concrete.
There is a self-leveling polyurethane in caulking tubes that works well for filling joints and small cracks in concrete. I believe the brand is Sikla or similar.
For cuts that small in a solid slab you are better off with something hard rather than caulk. You can finish it flush with the surface easily. Caulk will sag, will be too flexible for epoxy to adhere to, and isn't needed where there is not movement in the joint.
I think epoxy would be best, or a cement slurry.
Bob, my recommendation is to check out the UCoatIt website:

They offer a wide variety of epoxy concrete patching compounds in addition to their epoxy floor coating system. I used the epoxy floor coating in my garage earlier this year and recommend the product to anyone considering a floor coating.

Vulcum ans Sika make a self-leveling polyurethane in caulking tubes that works really well for for this kind of application.
