Thanks for your reply. After amending TY2020, I've tried to amend TY2021 after backing up. But TurboTax
would not allow me to overwrite the "prior year Unallowed Loss" in Form 8582 Passive Activity Loss Limitations Part IV. The "Edit->Override" choice is greyed out. How do I work around? If this is not the place to override, then where can I do it? Thanks! BTW, I need to do this operation for 3 consecutive years.
