Where do I mark that I did not receive 1098 for Home Equity Loan

Where do I mark that I did not receive a 1098 for my home equity loan?  I have a home equity loan, but the interest was under $600, so I did not receive a 1098.  One of the other answers posted said to mark that I did not get a 1098, but I do not see a place to do this.

In addition, do I have to fill out the other fields, other than the interest field, such as mortgage balance, etc?  If I do, is this the balance of the home equity loan, or the actual mortgage, which was through a different lender?

Thank you!
