Keep getting the hmmm... looks like we've hit a snag. Check your internet connection and try back later. Everytime i try to finish and file. What can I do?

Connecting to the Internet is required to update TurboTax and ensure your completed tax return is accurate and ready to file.

 

To check your Internet connection:

• Open your browser and go to a website that you haven't visited in a while. If you can't access the site, your connection isn't working. Contact your Internet service provider for assistance
