You can use Windows search to look for it. Or check C:\Program Files (x86)\TurboTax 2023, which is the default installation location.

I uninstall and re-install from the 2023 CD and search again in your captioned folder, but there is still no such tt2023.exe is found. Only a tt2923.exe.config file is found. And still I cannot open a 2022 file from my USB using this 2023 version with my new Window 11 laptop.

Please try using the download from our website to install the program. You can download TurboTax from here: https://turbotax.community.intuit.ca/community/product-information/help/where-can-i-download-the-cd-...
