If you have an SD 100, it means you live in a School district with an income tax. Although
administered by the Ohio Dept. of Taxation; an Ohio School District Income Tax
(SDIT) return is completely separate from the Ohio State Income tax. It has nothing to do with Schedule A on the state return.
As for the Ohio state return, "itemizing" is a misnomer. Unlike the federal return, there is no standard deduction. So there is no choice between standard and itemizing. Certain expenses are allowed to be deducted form your income. Only one of them just happens to also be a federal itemized deduction (medical expenses).
