"re do we need to enter anywhere ?"

Yes, enter the W2 info. No, don't enter the informational box info. It's already a subset of the main boxes, so it is already taken into consideration.

This is no different for any other W2. Box 14 is information. You would only enter that piece of info, if it matters somewhere. Example: tracking some sort of Basis, or a child care deduction, or clergy deductions that apply to their SE activities.
