Basically, you don't enter the 1099-S anywhere. But the fact you received a 1099-S means the IRS has a copy of that 1099-S. So you are required to report the sale *no* *matter* *what*.
You need to start your tax return over from the beginning so you can re-import the rental data from the .tax2017 file. To do that, close the program completely. Then delete the .tax2018 file located in the documents/turbotax directory. Now fire up TurboTax 2018 again and it's "as if" you are starting the program for the very first time.
Now, because of a lack of clarity in tax law, when asked how many days you rented it in 2018, you ***MUST*** enter at least 1 day. The fact your rental income for the 2018 tax year will be zero doesn't matter and it's irrelevant. Additionally, your days of personal use will be ZERO.
So work it through again using the guidance below and please post back if you have more questions.
