I just found out the same exact thing happened to my 2020 return as I was wrapping up 2021 return. The loss carryover amount was not transferred from 2019 tax file to 2020 and the return was filed without the loss carryover on 2020 return. So what do I do now? Should I amend 2020 return first and file an extension for 2021 return?
