If I were you, I would download the 1098 form from the IRS see pertinent information the form is looking for,
find that information from you financial institution, for example December 2019 statement.  If you have an on line account at your financial institution where you have your mortgage even better.    Go on line and get a copy of your 1098 for tax year 2019.
