I have several items of investment assets to be depreciated over time and they are in TurboTax since day 1 (several years ago). This year when TurboTax transferred the previous year tax form, it did not get the prior depreciation amounts correctly. E.g. some of the prior depreciation is larger than the total initial cost, which triggered an error in the final review. I went back to the investment expenses section and corrected all the "prior depreciation" amounts using the numbers from 2019's form 3885A (prior depreciation + current depreciation columns). However after all is done, the 2020 form 3885A is still showing prior depreciation amounts different from my input. Some of these amounts are larger than the initial cost of the item and I assume they are incorrect.
I also tried inputting 2019's prior depreciation column only as the "prior depreciation" amount in the investment expenses section. The 2020 from 3885A still shows seemingly random prior depreciation numbers different from my input.
How to correctly input the prior depreciation amounts?
Thanks.
