Tax Year Prior to 2020: Divorced in 2018, liable for part of the interest earned, account was in wifes name?

[skeeter76]

I got divorced in December 2018.  We had online savings accounts, in my ex's name.  In the decree, it says I am responsible for x percent of the interest earned of one of the accounts.  She received the 1099 INT in her name.  How am I suppose to claim the interest, just calculate how much interest I am suppose to claim and act as I got a 1099 from them and enter it?  Or does she have to file for the amount on her 1099 and I have to pay her?  Not sure how to go about paying my share.   Thanks....

Yes, just enter the amount you are required to report.  The 1099-INT form doesn't get filed with the tax return itself.  Since it came in her social security number, she will adjust off the amount she doesn't have to report on her tax return.
