So far, I've tried:
- Checking to make sure all update are installed (TurboTax says I'm up to date).
- Manually updating TurboTax Business per instructions here.
- 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.
- 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.
