Investors & landlords

This trail was very helpful. I have a question though. We had a rental property since 2013. We never had any income any year, as expenses exceeded income. But I can't find a form 8582 for any years except for 2018 and 2019. Why wouldn't TurboTax have created 8582s for those other years? Could we have exceeded some sort of income limit on our W2's to show a passive loss those years? We sold in 2020 and TurboTax only shows those 2 years of losses - at $9k or so each year. In addition, on my old schedule E's, it appears the depreciation varied from year to year. Why would that be?
