Why did TurboTax claim a "military" deduction for my regular Social Security income?

State of Michigan is disallowing a deduction for the full amount of my Social Security retirement income that was wrongly entered by TurboTax as a military benefit. It used to be possible in TurboTax to look at the actual form and click on a box to find out what it pulled from - but that is no longer possible. I have NO idea why it would think I qualify for a military deduction here, or whether it actually went in as just a Social Security deduction (which ought I think to have been limited to non-retirement Social Security benefits). The result is that instead of several hundred dollars refund, I owe Michigan a bit over a hundred dollars. Any clue what might have happened?
