From what I've read, it doesn't appear that there is a fix at this moment. Your best bet is to file by mail. I know it is frustrating. Though, before you do, if you're a LIVE customer, have a tax expert see if they can help you file with the line-by-line review service that the product offers. LIVE is a free upgrade for basic filers at this time. If they are unable to help you send your E-File successfully, then TurboTax would happily refund your product. I'm sorry that you are encountering this problem.
