Go to:

Personal Income > I'll choose what I work on> Less Common Income> Miscellaneous Income (last item at bottom of the page) > 4th item down should be 1099-LTC  

or you can search in the find box, upper right hand corner: "1099-LTC" then "jump to" and it'll take you right there.

This is not taxable if used for medical expenses, but you should report it for informational purposes.
