I still have a valid Ohio driver's license. I'm also registered to vote in Ohio
There's a way to handle this, but I honestly can't tell you what it is. Perhaps the below will help you, or assist someone in helping you to get on track.
Basically, as a U.S. Citizen, you "must" have a "tax home" state or U.S. Territory. Period. I get the impression that for you, that state would be Ohio.
So on your federal return, your home state (for tax purposes) is Ohio.
Then it's when you get to the Ohio state tax return (you "resident" return for that state) that you deal with (somehow) your physical "residency" status for state tax purposes.
