Weather you retire an asset, remove it for personal use, sell it, burn it, blow it up, haul it to the landfill, whatever, the correct procedure is to show it's disposition on the tax return. The year you show the disposition of the asset, will be the last year you need to show it on a tax return.
That's why I stated that if it does get imported into the next year's taxes after dispostion, you can just delete it from that next year's tax return. For a disposed asset, the program is not supposed to import it the next year. But sometimes it does so anyway.
