Just tried it. It's working fine. You may just be looking in the wrong place*. Also check to see if any of your SS benefits were taxed on the federal return*. If not, there will be no deduction, on the OH return. Line 14 of OH Schedule A should equal line 5b of federal form 1040.
Otherwise, I suggest you delete the SSA-1099 and start that part over. It's almost assuredly an entry error.
*You may be looking too soon. TT will not have calculated a taxable portion until you have entered sufficient other income.
