Yes, it will. TurboTax Home & Business 2021 updated on 2/11/2023 just deleted my data on my 2021 file dated 2/03/2022. Unfortunately I did not have a backup and will now have to redo my 2021 return. And I made an error in overwriting my old file (should have Saved As, not Save). ALWAYS HAVE A READ ONLY BACKUP someplace else to copy from.
