Should I amend my 2020 tax return if I received a corrected W-2 from my employer and the only box that changed was 12W for employer HSA contributions?

If entering the corrected w-2 changes any lines on your 1040 that results in a change in your taxes, I would file because it's likely the IRS will send you a notice though you might not get it for a year or two.  if no changes. then do nothing.
