I got bit by a 2020 bug in Turbotax whereby the passive carryover loss on a rental property was not transferred from my federal return to my california state return. I checked the 2020, 2021, 2022 returns and the passive carryover loss, while wrong, did not impact the amount of tax due, in he CA state return (federal returns were correct). Now I will fix that for my 2023 return and enter the correct total carryover loss in my california state return so 2023 CA state return will have the correct passive carryover loss amounts. My question is since there is no changes in tax due, can I just submit the correct 2023 CA state return, or do I need to amend the 2020, 2021 and 2022 california returns even though there is no change in tax due?
I am a bit irritated that Turbotax does not notify users of bugs and when they are corrected and leave it to the poor users like me to find out years later! The only way I found out was doing a search and discovering that this bug occurred in the 2020 version of Turbotax.
