Hello, first it's a pleasure to be able to help you today.

My name is welcome to the community.

Hello Lupita, if you have access to your Microsoft account you can check the link below if there is any service linked to it.

I play Minecraft on my PlayStation 4 so that's the console I'm having issues on. I'm not really sure what you mean by third party account as Microsoft only lets you link things to Microsoft approved/partnered things, but it was my Xbox/Microsoft account, I changed the Xbox account's randomly generated username to a new one and that's when I first started getting problems logging into my Microsoft account on the PlayStation but it still let me log back in eventually, then I changed my Xbox username to match my PSN username and now it doesn't let me log in at all.

Unfortunately, you cannot see which PSN account is using the Microsoft account!

The only thing you can try is to check with PSN if there is any possibility to figure out what PSN account is using the Microsoft account,

Yah, I'm having this same issue. I don't think I have ever linked my PSN account to a Microsoft account. Yet, Microsoft states I do. I have scoured everywhere I might be told of which Microsoft account I have linked to my PSN account but, to no avail (Microsoft account access on a PC, my PSN account on my PlayStation device, my PSN account on a PC, Mojang's website.) I even tried that backward fix of changing both passwords. Nothing. I agree that the bare minimum should be to tell us what Microsoft account is currently connected to my PSN account but, we don't get that.
