When you were completing the 2016 tax return with TurboTax, in the Rentals and Royalties section you had to tell the software that you were no longer using the rooms as a rental. Since there was no asset to depreciate in 2016, the software did not prepare a depreciation report for 2016. The same for tax year 2017 and 2018.
If you saved a PDF of the 2015 tax return to include all worksheets, there will be a Depreciation and Amortization Report which has the total depreciation for the rental rooms from the time you placed them into service as a rental through 2015. If you do not have the PDF, then you will need to start the 2015 TurboTax program and Continue the 2015 tax return. Then go to Forms mode and the Depreciation and Amortization Report will be available.
For the home sale you enter the total deprecation to be recaptured where asked in the Sale of Home (gain or loss) section of the TurboTax program.
