TurboTax Business VALIDATION ERROR Code 54 so we cannot efile

[johnp317]

I am not able to eFile my return even though I have all updates.  I tried restarting TurboTax, the computer, turning off Norton firewall, and making sure I have all updates.  I still get this:

Checked for update shows no updates, but Transmit still gives error.

Try manually updating the software. Here is a Help Article that will walk you through it.

I downloaded and installed the manual update and got the same error.

Also uninstalled and re-installed TT For Business 2025 and still get error.  Latest update is today and supposedly installed successfully...

@KristinaK Thank you for the reply. Your link is for TurboTax Deluxe, but I have TurboTax Business.  I manually downloaded and updated from the TT Business page here:

https://ttlc.intuit.com/turbotax-support/en-us/help-article/update-products/manually-update-turbotax...

and I still get the same error.

So far, I've tried:

1. Checking to make sure all update are installed (TurboTax says I'm up to date).
2. Manually updating TurboTax Business per instructions here.
3. Uninstalling all versions of TurboTax and TurboTax Business, downloading the latest TurboTax Business 2025 (on 2/1/2026) from my Products & billing and reinstalling it clean.
4. Uninstalling Norton 360, restarting TurboTax Business, checking for updates again, running smart checks again.

NONE of these solutions work.  I get the same error when trying to transmit every time.

INTUIT, we need your help on this.
