Deductions & credits

Thank you for the information that you offered and for your timely response.  Just to help confirm that I am understanding this correctly - Working with Ohio form IT 1040, Schedule of adjustments, I would enter the amount from IRS 1040 line 6B, $20,000, into line 14 for taxable Social Security Benefits.  Then I would also be able to enter the amount from my 1099-R, $13,000, into line 34 for Medical Disability Benefits and use the total of $33k for my deduction on line 2B of my Ohio IT 1040?  And I can do that for 3 more years until I turn age 65 when my disability pension converts to a normal retirement pension?
