Why Car Expense error?

I am filing 1040 for two people each with Schedule K-1. One person has car expense and that's fine, the other doesn't but has a car attached from last year. However, there is an error on line 6a. 5c has total miles driven. 6a has 0, 6b has 0 and 8 ha the same as 5c.

 

So why is Turbo Tax flagging an error? And how do I get rid of it - seems like by now this would not be a problem so I can file my taxes.
