The review is citing a W-2 because there is one still in the system that needs to be deleted. The easiest way to get to this and delete it from the return is by switching to the Forms view (Ctrl+2) then typing "w-2" into the Open Form search then double-click on "Form W-2: Wage & Tax Statement" to open the form. When it populates on the main screen, click "Delete Form" at the bottom of the screen.
