I have used Turbo Tax for many years. It used to provide the basis of rental property. I cannot find it on the returns for 2016 or 2015. Where would I find it?
When you save your tax return as a pdf did you ask it to save all reports and worksheets? If so, open the pdf file saved for 2015 and look for the deprecation report. This report has all the assets listed with their basis, etc.
