Retirement tax questions

Maybe if I could ask another question.  The 1099-INT is over 600.  She passed on 9/4/19, the 1099 was issued at year end 2019 but issued to her and under her SSN and not the estate Tax ID that I created.  Can I include the 1099 under a personal income tax return form 1040 or is this 1099-INT required to be filed as part of an estate tax return form 1041 using the estate tax ID?
