Where on my prior year's (or years') return do I find/figure the amounts for "Prior Depreciation" AND "Prior AMT Depreciation" for my vehicle which was bought new and put into service in 2015 for a 1099-NEC business. I AM NOT using standard mileage deduction, but rather entering expenses. A tax professional prepared my taxes last year, but every year prior I have used TurboTax for filing (if there is something to be learned from 2019 or prior years' taxes). I've looked on Form 4562 and related schedules, but it is unclear to me which lines/columns to use. Help would be greatly appreciated.
