Not sure if I filed correcting, amend for schedule B interest on foreign bank account

Hi, I filed a US tax return for the first time for 2024 and 2025. I earned interest on a bank account in my home country but it was a business bank account and a nil return was filed on that business. The business never functioned but earned interest on money I had put into the account.

I filed late FBAR and used the delinquent filing. I did not claim the interest earned on the account because a nil return was filed for business.

Do I need to do an amendment? My husband and I ended up doing our own taxes. Yes I already know that was probably not good to do but his accountant had health issues and we did them.

I want to fix this but not sure how to. I have done the FBAR and said I did not know I needed to file which is true.

I would appreciate getting feedback. Thank you
