How do I find out where HMRC get their estimate of untaxed interest? I would like to know which organisations have provided HMRC with information and what that information is.

I got a tax code notice yesterday with an estimate of untaxed interest for 2024-25 based on the amount for 2023-24. In 2024 I shifted most of my savings into ISAs so this estimate is wrong. Will my banks report this or do I have to do it?
