FAILED_VALIDATION error when trying to file

[WRHoff]

I got this error filing my 2022 taxes in April 2023.  I looked through all the myriad suggestions on several sites.  Tried the simplest ones such as killing TurboTax from Task Manager (Windows machine).

None worked.

Figured I would try something radical.  I REBOOTED THE COMPUTER and tried again and it worked on the first try.

So why would that be so?  Something to do with the Cache?  I don't know but it worked.

That is one suggestion I have not seen here or anywhere.

could be that the latest update was downloaded but not installed and on reboot it was but you didn't see this  - only a guess.
