- Update Software: In the TurboTax desktop app, go to the Online menu and select Check for Updates.
- Manual Updates: If the auto-update fails, download and install the latest Manual Update patch
- Disable Security Software: Temporarily turn off VPNs and third-party firewall/antivirus software during the update and filing process, as they can block validation.
- Reinstall/Repair: Uninstall the software and reinstall it directly from your Intuit My Downloads folder to ensure you have the latest, uncorrupted version.
- Run as Administrator: Right-click the TurboTax icon and select Run as Administrator before attempting to update.
- Try Federal Only: If filing state and federal together fails, attempt to transmit the federal return separately.
