I experienced the exact same issue...and fixed it. It appeared to be related to a $0 item (without a description) listed in my deductions/depreciation assets. The easiest way to fix it is to ignore the error and continue through until the review section. Turbo Tax will identify the problem areas and prompt you to fix exactly what is "broken". You can always verify that it's fixed by revisiting the problem section. In some situations, you may have to go back and delete invalid entries (which in my case were a few no description $0 items)
