If you used the Desktop programs the tax return files are only on your computer. You only need the files ending in .tax2022 to transfer into 2023. Both the Business returns and personal returns use the same ending .tax2022 extension but the name should show which kind it is. Do you have the .tax2022 files? They should be in your Documents in a Turbo Tax folder. Or search your computer for all files ending in .tax or .tax2022.
Do you also need to see your prior returns? You need to save a pdf copy each year. They should be in the same location. You don't need to install the older programs unless you want to open the .tax files like to amend them.
