Investors & landlords

Any reason why it would have been a different amount in 2017, 2018, and 2019?? I used the original purchase date and price then added the date we moved out and it became a rental. I don’t have exact but know the month and year. I have used TurboTax for more than 10 years and it has always transferred it, but for some reason it made me start all over this year even though I imported the pdf. Thx!!
