Married filing separately- How do we treat the question about how much is owed on the mortgage as of January 1, 2018? Split it or both put the full amount?

[cfmayhew1126]

So we are married filing separately. We split the mortgage interest deduction. This year with the new law we are also asked -- what was due on the mortgage on Jan. 1, 2018 and what was due on Jan 1, 2019? Do we both list the full amounts or split this amount also--like we are splitting the interest deduction?

No report the full amount because both of you are on the mortgage.
