Form 4562 will automatically be generated for prior year assets if you are using TurboTax Home & Biz. Other lower versions (Deluxe, Basic, and Premier) do not support business expenses, including depreciation. You will either need to upgrade to Home & Biz or manually enter your assets and depreciation. They won't be transferred over unless you are using Home & Biz. You can use Forms Mode to manually enter these forms/expenses if you are using a lower version.
You can look at last year's return to see the amount deducted for depreciation in 2016.
