@ChaseFamous - when you lowered acceleration and jerk the bump in the corner got worse. That is exactly what I would expect. What happens is with the lower acceleration it takes longer to slow down and speed up going around the corner and so the higher pressure in the nozzle at that time means it over extrudes. Better to crank up acceleration and jerk and only lower speed: if the speed never slows down on the corner then the pressure in the nozzle is always constant and you don't get overextrusion in corners.
However I would expect at least 3 of the corners to have that bump if it was an acceleration issue. Instead it's probably taking too long to change layers (which usually happens on an "infill" layer). Make sure "retract at layer change" is disabled as this can cause more delays where filament is coming out of the nozzle. Also make sure your Z speed is as fast as possible for your printer. Both in cura and in the firmware of the printer.
@mccleary39 - I don't think you are having the same problem as chaseFamous only has one blob in the corner. Right? maybe you should start a new thread or at least post a photo of your issue.
Both of you: ironing is a little tricky - neotko is the expert on this feature. Read all of his posts on this thread:

Hello, I am having the exact same problem with my part. I have holes that I am trying to iron around and it is making large "blobs" on the surface. Did you figure out how to get this fixed?
Thanks!
