Error Code 54. Same as others. Why is this not fixed?

We are looking into this issue. Watch community for an update.

Here are several troubleshooting steps that you can try:

• 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, or you downloaded TurboTax from a CD, try a manual update. What is a manual update?
• Turning off your VPN and anti-virus software during the update can help as well.

UPDATE:

This has been resolved. Please run an update and try filing again.

Please let me know if you are successful.

This still hasn’t been solved & I’m experiencing the error in Intuit TurboTax Business 2023 & am unable to file my federal or state return.

See this thread on how a user solved this: https://ttlc.intuit.com/community/taxes/discussion/re-failed-to-e-file/01/3286619#M1208968

Thank you so much! That was the solution.
