Are you saying your 2023 tax return file ending in .tax2023 is in your program files? You should move it to your Documents. It should be in a Turbo Tax folder under Documents.
To Transfer 2023 into 2024 you need to start a new 2024 tax return (go up to File-New Tax Return) and if your 2023 return doesn't show up to transfer then click on Find a Tax File and find the .tax2023 file. You can only transfer into a blank new 2024 return.
