State tax filing

Thanks.  But I just got this answer from Ohio tax help center:

“If you made a non-qualified 529 withdraw that income should already be include into your federal adjusted gross income and be taxed on the state level.“ (sic)

Maybe the person is misinformed or didn’t understand my question?

It still seems strange to me that Ohio would forego taxes on non-qualified earnings, but I hope that answer is correct!

Any further help?  Thanks.
