And yes, the .tax2021 datafile will transfer your carryover loss data.
But you also want to download all prior tax years of PDF files to your computer for future reference.
Once you get out of the Online software.....you may lose track, or access to that online account to get those PDF files at some time in the future, so get those files NOW.
Might be a good idea to get the .tax2019 & .tax2020 datafiles while you are at it, just in case you have to amend those years for any reason. The IRS could still start asking some questions about those...as those years had a mess of confusing changes.
