MFS to MFJ amendment. I have a client who lives in WA and has a rental property in CA. She got married this year and her husband already filed a 2020 MFS return (ugh). I understand that the best way to handle is to amend the husband's return and add her info. But.....she has all this carryover data for the rental and other things. How can I do this without having to manually move over all of her rental stuff? Or, do I have to create his MFS return, amend and then add all of her stuff (nightmare)? Any tips?
