This has been a known issue in the Mac desktop software, but many people have been able to use a simple workaround. Here are some things to try:
- First make sure the 2024 data file is not password-protected/encrypted in the keychain.
- Then close TurboTax completely. Then re-launch it, and try the transfer again. For some Mac users, that simple maneuver has solved it.
Or
- Close TurboTax completely and restart your computer. Relaunch TurboTax and try the transfer again.
Or
- Try to open the *.tax2024 data file with the 2025 program. It may say something like "This is not a 2025 data file, do you want to transfer instead?"
