Investors & landlords

Thanks for the responses and the NOL seems exactly what I need to do.  I had just one rental property and therefore only one year of NOL when I sold the property in 2018.  I am sorting through the worksheet and will see if I need to post back with any questions.  However, one immediate question is, once I calculate the NOL for 2019, where will I insert it in my 2019 tax forms and, since TT does not calculate it, what do I include as supporting documentation.
