Failed Validation Error Code 54

I'm trying to file my Federal 1041 and CA 541 for a trust with TurboTax Business. I keep getting Failed Validation Error Code 54, even though I've downloaded all available updates. This seems to have been a problem in prior years as well. Is there a fix available?

If you're still having trouble validating your federal return, we recommend you try a manual update: Manually Update TurboTax for Windows Software.

 

We also recommend suspending any antivirus software and/or a VPN.

Does this link manually update TurboTax Business, or just regular TurboTax? I am reluctant to download a random piece of software. Can't TurboTax fix the problem in the software?

This proposed fix does not work. Will the software be updated so that we can file electronically?

Validation Error Code 54 should be fixed now. Please update your software and try again. Thank you!
