unending loop ohio school district taxes

I have 2 employers in ohio in same school district. The boxes on my w-2 are both complete boxes 16-20. I keep getting these messages: Schedule SD WH: w2 school district tax should be entered on federal form w-2 Box 19 for the school district number entered above. It's never clear what they are referring to and scrolling up it looks like all the information is on the SD 100 form and the totals are correct. I can't get past this error message. what do i do?? thanks!
