What do I do when the Federal review hits a snag and cannot continue?

This is the message: "Hmm, looks like we hit a slight snag in this section Let's get you back to your taxes. Make sure your Internet is connected, and then select Try again or check back in a few minutes." I have tried a different browser and checked back over several days. The AI help has told me that this is a known problem and will not give any assurance if or when it will be fixed before the filing deadline.
