First, I need to make sure I understand one thing. Are you saying the asset did not transfer from your 2016 turbotax file into your 2017 turbotax file?
If this is for business property reported in the Business Assets section, you'll find it on the 2016 IRS Form 4562 that has that asset listed on it. There are three 4562's in the package. You want the one that prints in landscape format specifically titled "Amortization and Depreciation Report". If you still have TurboTax 2016 installed on your computer and need to know how to get the specific 4562 you need, just let me know. It's also important to note that a part of the depreciation that needs to be included, if the asset was "in service" in 2017, will also include the allowed depreciation taken in 2017 prior to you selling it.
