To continue linking your EA Account, head back and start over.

I did see that mentioned online but I don't believe that I actually have any other EA accounts other than the 1 that I made fresh to test today, but I'm also the same as you where I checked to see what linked accounts I had (on Epic and EA) and there is no sign of either of them being linkable on the account management side of things, would be a lot easier if we could just link the accounts through that screen
