Did you open the 2024 app to see if it can find the return? Another approach is to look in the Turbotax folder in your documents section. If there is a file starting with a tilde (~) and ending with ".tax2024" that might be the back-up file that can be opened
the location of the last time used is stored in the registry
hkey_current_user\software\intuit\turbotax2024\recentfilelist\s2024us1040per > under this key.
