All versions of TurboTax are operational, and some people have filed tax returns. What exactly is TurboTax "not completing"? How do you know that Form 1040 is not complete? Are you looking at the actual Form 1040? What's missing on Form 1040?
While many forms are available for filing, including Form 1040, there are still some forms that are not available yet. Is your problem that you need a form that is not yet available? You can use the Tax form availability tool to check the availability of specific forms.
