form 4562 does not show the total depreciation taken in all the prior years, just that year. if you always used TT the depreciation history for an asset is with it and should be available in forms modes by clicking on the link for the history. The other option if you have the 4562's for all prior years and just that property add up the amounts. however, TT follows the tax laws and does not produce form 4562 in years where no assets are added.
