How can I use my daughter’s Form 1098 to get a tax deduction, if she died in February and I inherited her house and paid her mortgage from February on?

If the mortgage interest shown on the form 1098 for the year is $10,000, how can I get credit for all of it if I didn't pay for all of it? I think my daughter paid the January mortgage bill (though I gave her the money, but that would be hard to prove to the IRS)
