This is your oil tank and lines
# 26 is your drain plug, a 5/8 wrench should be what you need
Mine is different. It is embedded in the frame so I can not fit a standard socket onto the plug (because of socket wall thickness). So I have to use either a torx or an allen and I'm not sure which one or the size.

This video shows a standard 5/8 socket being used. Maybe yours has slipped up into the frame and you can push it down to expose the plug. UPDATED!! how to change the oil on a softail - YouTube

Thinking a 1/4 or 5/16? not too hard to check... Make sure it fits tight and I use the 90 end out with a 3/8 box end wrench over that 90 portion for turning leverage...
Normal turning is LEFTY LooseE,,, looking up at it.

Go to Harbor Freight and get set of allen. It is cheap and nice to have them in your tool box.

Buy yourself a thin walled socket or take a screwdriver and clean around the bolt head. The allen strips.
