Hi, I have a similar question. I used the wrong cost basis for my rental property from 2015 through 2021 (included my land value resulting in a higher cost basis, therefore a higher depreciation each year). Do I address this issue by amending prior 3 years' returns by adjusting the "Rental Properties and Royalties (Sch E)" section by manually entering the correct cost basis, prior depreciation, etc starting with 2019, then 2020 and finally 2021?
Thank you for your guidance
