Form 4562 Depreciation and Amortization reports business assets and the depreciation expense taken for the year. You should continue to take depreciation as long as you use those assets for your business.
The header of Form 4562 displays the Business or Activity relating to the assets on the form. If this is a Schedule C business, you would enter the info under Assets/Depreciation from the Business Summary page for your business.
Also look for a Depreciation Report that may refer to Form 4562 (see screenshot below - click to enlarge). From this report you will enter the asset description, date in service, cost, and depreciation taken.
