You treat the copies as if they are one W2. You will enter the Federal information as found on copy B (which is the Federal copy of the W-2), and then the Ohio information on lines 15-17 from copy 2, and, beneath that in TurboTax, the Indiana local taxes withheld in boxes 18-20 (associated with Indiana, not Ohio).
While Indiana and Ohio are reciprocal as states, the same is not true about the local taxes. However, the information may still be useful because your Ohio locality may give you a credit for the taxes you pay to the Indiana locality when you prepare your Ohio local return.
