Error code TT401

While I am completing my return I get an error code TT401 "An error occurred while saving your return".

I have checked that I have sufficient disk space so the issue seems to be related to write protection of the device disk.

I have noticed on previous years' TurboTax software that I always get a message "Do you want to allow this app to make changes to your device?", when I open the program.

I do not get this message when I open the 2025 version. I suspect this may be causing the problem.

Is this a software issue that can be corrected with an update?

If not, would deleting the software from my device and reloading it possibly correct this error.

Please advise. Thanks
