I have the same question. Too bad Turbo Tax does not automatically open a help window telling us how to find the answer. I hope I got it right. I went to last year's complete Fed tax forms, and towards the back I found Form 4562, This form is several pages long. Find the "Depreciation and Amortization Report", go to the line listing the item of interest, e.g. model xxx car, go to the corresponding column next to last titled "Prior Depreciation", and enter that number. Next find the "AMT Depreciation Report" (also part of Form 4562), go to the line listing the item of interest, go to the corresponding column next to last titled "Prior Depreciation", and enter that number. Again I'm not sure why Turbo Tax does not AUTOMATICALLY extract those 2 numbers from the previous year and populate the applicable boxes for the current year. So much more convenient!!
