I need to amend 2018, 2019 and 2020 returns within Turbotax to correct rental property days of personal use, depreciation and Form 8582 unallowed losses. I will amend starting with 2018, but how will the 2018 amendments feed to the 2019 update for amendment? Does Turbotax handle all of that or do I have to manually update forms all the way through to 2021? And I've already downloaded the 2020 data to start my 2021 return. Thank you.
