I got my 1099-INT from my Bank as every year. But this year, I got a 1099-INT form straight from IRS. What is this coming from? Do I have to upload both bank & IRS forms?

The only "abnormal" situation I had in 2024 (for 2023 taxes) is that I had to file an extension as couldn't make it for April 15. So I filed later but for a few months only.
