I am looking for a detailed depreciation schedule for my business assets from my 2015 taxes and cannot locate the correct information. Where would I find that?

Depreciation worksheets are not submitted to the IRS, so they are not included in a standard print out of your return. The first step is to look behind your main tax forms. If a tax professional did your taxes that year, you may need to request them. If you did your own taxes that year and you still have the desktop software, you can open that file (I would suggest not running updates) and print your return with supporting worksheets. 

Going forward with TurboTax, I would recommend always saving your return with supporting schedules/worksheets.
