When your ex moved out is irrelevant. You were legally married until the date the divorce was finalized. If that date was on or before Dec 31 of the 2019 tax year, then you can not file a joint return. Period.
The simplest way is to use my guidance above to significantly reduce the likelihood of human error on your tax return on your part.
Under no circumstances and with no exceptions will you *EVER* select the option for "I did not rent or attempt to rent this property in2019". If you do, then you will be *FORCED* to delete that property from your 2019 tax return. Extremely bad program design on Turbotax's part.
