Pictured here is my final PCB which perfectly suits my needs.
When I upload it to OshPark it ignores my Edge Cuts and expands the
size of the board to cover the whole of the MOSFET.
How do I correct this?

Ask them. I’ve found them very responsive.
But first I would view the gerbers to see what they are receiving in regards to edgecuts.
Are you sure all the lines and arcs of the outline are on the Edge.Cuts layer?
Maybe there are double, or overlapping lines on Edge.Cuts?
Does KiCad’s DRC complain?
How does it look in KiCad’s 3D viewer? (It used to be very picky about endpoints of lines matching to show the PCB outline, but it may have gotten some built in tolerance lately)
And what are you uploading? A KiCad project or only Gerbers?
And additionally I would check if the drawing on edge.cuts is really closed in between all elements. Sometimes the lines are off just by a tiny bit - especially when the original geometry was imported.
Sometimes the online software viewers are problematic. So, asking them is the first step.
Here’s my original goal.
To have my MOSFET (as seen is this pic) attached to a heatsink.
I struggled alot until a forum member helped me figure out that the footprint
should be ‘horizontal tab down’.
Here’s my 3d Viewer pic.

More in a minute.
The only thing the DRC complains about is where my MOSFET crosses
the edge cuts. This is a function of my design goal.
I’m uploading my KICAD files to Oshpark. Not Gerbers?

You seem to have a NPTH hole outside the board edge in the mosfet. Try removing that and other not needed parts from the footprint (basically you need only the pads and some guidance for orientation).

Excellent point.

The solution I came up with that appears to have worked is…
I got the proper MOSFET layout and orientation using the
‘horizontal tab down’ footprint. Prior to uploading to Oshpark I
switched the footprint to ‘vertical’. This seems to have solved
all the issues. Of course the final test will be when I receive the PCBs.

I think that it was the fixing hole causing this

I am guessing that eelik was right and the Oshpark gerber viewer gets confused by either the hole or by other things such as the silkscreen outside of the PCB Edge.Cuts boundary.
