Unending Ohio SD tax loop

Schedule SD WH: W-2 Ohio ID Number should be entered on federal Form W-2, Box 15 for the School District Number entered above. I keep getting the error above, and it is asking that I type something into the box 1 column in row 5. I have two entries to the same locality, so there are 2 lines here. I tried putting the Ohio ID number for my employer but it wouldn’t let me type a dash and instead inserted commas making it read “000,000,000.” What do I need to put in these boxes?
