You do NOT amend your Ohio return. The school district return is a total separate filing from the state return and can be filed separately, although it may have to be mailed, instead of e-filed.
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
2018 Ohio Taxes are ready for us to check"
-Click Other situations
-Scroll down to School
District taxes.
