IN has a specific form (IT-40RNR) for a reciprocal state refund. Rather than paying TurboTax for IN software, you should try filing that form by hand. It looks pretty simple. Get it here: http://www.in.gov/dor/4733.htm
The reciprocity agreement does not apply to local city & county taxes (box 19 of the W-2). You can not get those refunded, but if you live in an Ohio city with a tax, they may give you a credit or partial credit. Many do. You need to check with your city.
If you are subject to Ohio School District Income Tax (SDIT), you can not get a credit, for IN county taxes paid, on an SDIT return.
