If she worked in Ohio and is a resident of West Virginia she does not have to pay Ohio income taxes on her wages. If she works in OH in the future, she can submit exemption Form IT-4NR to her employer so they don't withhold OH tax.
First, she will report all of her income on a federal return. Next, she will complete a nonresident tax return for OH. Nonresidents can claim a credit on Ohio Schedule of Credits, for income not earned or received in Ohio. TurboTax will guide you through the return. And lastly, she will complete a resident West Virginia tax return.
When would I have to file returns in more than one state?
