In Box 14 of my W-2 there is a category I need to input labeled 401(k) ER. However, Turbotax doesn't have 401(k) ER in the Box 14 - Category dropdown.

I don't think you need to report the employer portion.  That's probably just for your info.  @dmertz

Right, just info.  Don't enter that info into TurboTax.
