Thank you the responses. Employer replied back that they didn't see a need to update the W2 and I can just use the box 20 value from the email (in quotes below) v/s what is in the W2.
e.g.
"Transit Authority" instead of JeffCn (W2 value)
"School Boards Tax" instead of JeffCn (W2 value)
"Jeffery County" instead of JeffCn (W2 value)
