every time the OS updates it tell me an application has an extension that won't be supported in the future. but it does not tell me what application or even what the extension is.
any idea on how to find it?

I think Apple did a very poor job of explaining this. But hopefully they handle it better once it happens.
You should always wait a few iterations of a new OS to get the bugs worked out, that's likely a year from now!
No need to worry, but to see them, just don't upgrade to 10.16 or iOSXi, or whatever Big Sur is if the developers don't have updates...
