had foreign bank account and I received interest for 2024. But should I fill my interest earnings from foreign banks in the 1099 int form or fill fbar or both

You will report the interest income as if you received a 1099-INT.

Where do I enter Form 1099-INT?

You need to file FBAR if the aggregate value of your foreign financial accounts exceeds $10,000 at any time during the calendar year.
