If your 2019 W-2 shows OH withholding in Box 17, you'll have to request a refund by filing a 2019 non-resident OH tax return.
You will enter the zero OH income on the non-resident OH return.
It's not necessary to use TurboTax for this. Ohio offers a free fill-in PDF tax return here: https://www.tax.ohio.gov/portals/0/forms/ohio_individual/individual/2019/PIT_IT1040_Bundle_FI.pdf
You may want to attach a letter explaining why your return shows zero OH income.
