I specifically remember converting it to 100% on the year I gained full ownership in 2012.
Don't know your details of how you did it or how you acquired the percentage you did not own prior to that. But be aware you can't just go into an asset and change the ownership percentage number. When you do that with TurboTax, it completely skews the depreciation history big time, and makes your current year (year you changed the percentage) flat out wrong. Every year after that will be wrong too.
