Do not open a .tax20yy file by clicking on it in Windows Explorer. Start TurboTax, then open the file by selecting File > Open Tax Return from the menu.
The screen that says "Good News! We Found Your Tax Info" is looking for 2022 tax returns to transfer information into a new 2023 tax return. It is not looking for existing 2023 tax returns. You got to that screen because you clicked "Start a New Return."
Save your current (2023) tax returns on your hard drive, not on a USB drive or other removable media. TurboTax doesn't work well with removable media. You can copy the .tax2023 file to the USB drive for backup.
