There is a 1 1/4" black hexagon nut (cap) on the front of the engine, in front of the injectors, right of center when facing the windshield and under the hood. The oil filter is in there, under that screw in cap. Cartridge filter, not a spin on. Look for the big 1 1/4' nut. You'll need an extension and a 1 1/4" socket on an extension to clear the other braces and parafinalia. Easy to do with the proper tool. Don't over tighten it.
