Ohio has both city (municipal) and School District Income taxes. Form SD-100 is for the School District, not city.
There are 2 state wide agencies that help Ohio Cities collect City Income taxes. One is CCA (Central Collection Agency) and the other, larger one, is RITA (Regional Income Tax Agency). There is a pull down list of cities, in Turbo Tax(TT), for both City Tax Forms (CCA) & RITA. TurboTax can only do RITA & CCA cities. But many Ohio cities use neither agency. These cities design their own forms and require you to use them. You can get paper copies from the individual city. Most are available at the city’s web site. Many cities will prepare the tax return for you, but you have to go to city hall in person. Some may have on line filing (try the city web site). Although they won't usually admit it, some will even accept CCA forms. So you could try filling out a CCA form on TurboTax and mailing it to your city.
TurboTax (TT) does not automatically prepare a city return, you must initiate it. At the screen, in the Ohio program, titled
"A few things before we wrap up your state taxes"
scroll down to Ohio City taxes.
Or, later
"Your 2021 Ohio Taxes are ready for us to check"
-Click Other situations
-Scroll down to Ohio City taxes.
TT cannot e-file an Ohio City or RITA return. It must be printed and mailed.
I actually find it easier to fill out a city return by hand or at the city, CCA or RITA web site, than to use TT. Things don't happen automatically and you need to know what you’re doing. The actual RITA/city forms are easier to follow than the TT interview..
