I don't know. The Ohio instructions, for that credit, conclude with "See R.C. 5747.72", which says:
"The tax commissioner may request that a qualifying taxpayer claiming a credit under this section furnish information as is necessary to support the claim for the credit under this section, and no credit shall be allowed unless the requested information is provided".
I take that to mean, you don't provide it unless they ask for it. I don't think ODT wants to have to process that extra paper work. I would not send anything, especially if you are e-filing.
