I just took my number from line 2a and put it into Line 16 (state distribution) as noted above, resubmitted my SD 100 Ohio School District forms. Accepted right away.
I think this my 6th submission, trying to find differences this year from last, to no avail. Looks like Ohio SD changed something, because it went right through last year.
I also don’t know why the Ohio State taxes didn’t flag the same thing.
