When entering my 1098 my box 2 is a zero. But when I enter a zero Turbo Tax says it must have a value. There is no value on my 1098. What do I do?

I have two 1098's from two different Lines of Credit that we had last year.  Neither of them have any value in box 2.  When I try to enter these in Turbo Tax says it must have a value and won't let me continue.  How do I remedy this?
