CD Interest should be attributed to Mother or her Estate?

My mother had 2 CDs when she passed away in 2024.   The CD's were closed and the proceeds where added to her account and then the account was closed, and the funds were moved to her estate account, which was eventually probated. 

 

Her 1099-INT from the bank included the interest for the CD (which were closed a few weeks after her death).

 

Should the interest be included on her final tax return or should some/all be included as part of her estate?
