I also am having this same problem I cannot claim my prior losses (as per Rev Can Assessment) against 2021 gains. The line 25300 connects to a box 13 called "Available pre-1986 net capital loss that can be applied against other income in 2021" which has been calculated by Turbotax to be $0. Of course my Pre-1986 net capital loss is $0. Why is Turbotax calculating that amount instead of calculating "Net Capital Loss that can be applied against other income in 2021".
I believe Turbotax (downloaded version) has a software error that needs to be corrected ASAP so I can offset my Capital Gains against my Capital Losses from 2001-2020. If I override amount in line 25300, I will not be able to Netfile. I need a program fix or a workaround so I am able to NetFile a correct return. We have been using TurboTax for years without a problem so hope to get a fast resolution
HELP!
