It is possible that you never entered that it was the last year of that specific rental property, and the system thinks that you still have it. You should be able to open up the T776 that is not needed, then go to the top of the return, click on Edit-Forms-Clear current form, and then go back to Edit-Forms-Close Unused Forms. Any forms that you have listed that are not needed, please be sure to follow the same instructions above to delete each one.
Thank you for choosing TurboTax.
