I'm getting an error saying that Cashout should be blank on the Home Mortgage Interest worksheet, and it won't let me uncheck the circle. How to I uncheck the circle?

Thanks for posting this. I'm getting the exact same error. Though I was going crazy.

Anyone know how to notify Turbo Tax of this bug?

Select No entry on that screen, then click Continue.    Then click File from the left menu, then the Continue button again.   We are currently updating this in the review section, but you can bypass the question by choosing the No entry radio button.   @LostPilot
