Where on form does it ask how much I owed on house as of 1/1/19

[DanaB · Accepted solution]

The balance as of 1/1/2019 is not going to be listed on your 1098 form.  You will have to find the balance either on a mortgage statement or by contacting your mortgage lender.  

This information is needed due to the changes in the amount of mortgage interest that can be deducted beginning in the tax year 2018.  If your mortgage is refinanced or more than $750,000, then the ending balance is needed to determine the amount of interest that can be included as a deduction in 2018.
