File only the RITA return.
You normally only have to
file a return in the city you live in. It is not necessary to file one in the
city you work in, if different. Your employer will remit withholding to the
city you work in, but you do not file a return unless you're claiming a refund or
your employer didn't withhold enough ( both highly unusual). The city you live
in will allow a credit or partial credit for the withheld tax you paid to the
work location city.
TurboTax (TT) does not automatically prepare a city return, you
must initiate it. At the screen, in the Ohio
"A few things before we wrap up your state taxes"
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.
