Even though your
interest was not reported on an official Form 1098-E, you will still enter it
in the same section of your return as if you had the form.
You will just enter the name of your lender and the amount
of interest paid. Enter the interest
into Box 1. Then click Done.
See the information below to go directly to that section of
your return.
