I searched in One Drive, with no results. I searched using the different extension options you suggested, again no results. At this point, unless someone has another suggestion, I expect my TurboTax 2023 tax file cannot be retrieved and something caused it to be eliminated from my computer and One Drive backup. I will reluctantly have to reconstruct the carryforward data that that file downloaded to the new 2024 tax software. I expect that this and other problems encountered over the years with TurboTax will result in my no longer buying their tax software in the future, which I have used for decades.
If you or anyone has another idea, of course I welcome it. I do thank you for your trying to help.
