I had the same issue with Turbotax this year and the whole process seemed overly complicated for my very basic return. I never had a problem in previous years.
I didn't want to go through phone hell to speak to someone on the phone (having just spent 8 hours on the phone and hold in the 2 previous days dealing with a credit card fraud issue.) There should be an option to clear the form and start over, although from the comments here I would have hit the same block again. Or the problem question(s) should be highlighted so one isn't searching for a needle in the hay stack.
I ended up filing with another online tax service as I just wanted the forms submitted. Federal and state went through without an issue.
