Box 18 would report the local wages on which the local taxes listed in box 19 are calculated. So, you can't have local taxes without local wages. If you worked in the same place all year, the local wages may be equal to your state wages as reported in box 16. If you don't have an amount in box 16 you will have to ask you employer about the amount of your local wages and enter that in box 18.
