I've always used Turbo Tax. The Wage Tax is taken out of my paycheck so I think there was a somewhere to put that through Turbo Tax--local taxes. I never have done a separate return for the Wage tax. (And I have filed in PA/Philly since 2006).

If you have a business, you should have a business license, and can file your business taxes either on paper or online. I've always filed on paper, although once I think I filed online--that whole process has changed--before it was very antiquated.

If your wage tax is not taken out of your paycheck you can pay that (Earnings Tax) online:
