Hi Fumiko,
Unfortunately I’m not going to be much help here. It’s important that you go back to your previous tax returns and look at the depreciation schedules that were created by the tax program. The amounts that were taken for bonus depreciation and/or total accumulated depreciation should be on those previous tax schedules. If you need a good resource to locate a tax expert that can help you, I have listed below the link to our bookkeeper website and an article that has some good resources – both paid and free.
