FAILED_VALIDATION

Here are several troubleshooting steps that you can try:

• Make sure your Windows Software is up to date.
• If you are using a downloaded version, uninstall and reinstall the program from your MyDownloads folder.  How do I find my TurboTax for Windows software download?
• If that doesn't help, try a manual update. What is a manual update?
• Turning off your VPN and anti-virus software during the update can help as well.

If you are only getting this for your state return, try this:  State install/e-file update loop: State not installed after installation or TurboTax needs to update prior to e-file
