Deductions & credits

I have this exact issue too.  "If this is a qualified home equity loan, your balance can be zero on Jan 1, 2019 and zero on Dec 31, 2019, and still have a qualifying interest expense."

 

I appreciate your answer, but I do not think is explains how to handle this situation when it does exist.  How do I handle this situation where box 2 is $0.00?
