Can I be directed to the initial (full) depreciation schedule I set up for a rental property more than a decade ago with TurboTax? Thx

It depends.  If you still have the rental activity in your tax file, then you should see a depreciation worksheet. The rental property itself would be easy to calculate the full amount of prior depreciation using the 27.5 year chart (and individual years). Start with the month placed in service and all the percentage for all years together. Multiply that times your building cost portion.

It can be found in IRS Publication 946 and is posted below for your convenience.
