It has been a week since I finished my taxes and am ready to file but I get an error message saying 

This should not have happened. Don't worry - your data has been saved.

Our TurboTax application has stopped working properly. It rarely happens; we're sorry it happened when you were using it.

Tech support said it was a known issue, but so far, I haven't seen a fix. 

Unfortunately, I have to mail my return - and I would like to get it off and done with. Any idea when I am going to be able to use this functionality?
