State tax filing

Yes, technically.

Your "Ohio adjusted gross income" (line 3) includes the income earned in WV. 

You will owe no tax, so you could probably skip filing an OH return.

Ohio does a convoluted tax calculation for non-residents/part year residents. It calculates tax on total income, then it calculates a non resident/part year resident credit, which it subtracts from the tax it calculated on the total income. The credit is calculated as your non-Ohio income divided by Total adjusted Income multiplied by the total tax.  Since your actual Ohio  income is zero, your credit will be 100%.
