TurboTax (TT) does not automatically prepare a School District 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 School District taxes.
Or later at the screen "Your 2020 Ohio Taxes are ready for us to check"
-Click Other situations
-Scroll down to School District taxes.
If you don't have a form SD100, on your list of Ohio forms, you didn't file one.
At this point, you may actually find it easier to do an SDIT return by hand, than in TT.
