When A is being correct and B is wishful thinking, what I said is that A implies B

I think you messed up there. Being correct certainly doesn't imply wishful thinking. You were saying that non-wishful thinking implies being correct. That is ~B implies A. Or ~A implies B, which is equivalent.

If I checked my balance and due to some bank error was told that I had a large balance, I would probably have the sum be incorrect but still be using non-wishful thinking. The sum being correct is not a necessary condition for non-wishful thinking. All the other combinations are possible as well, though I don't feel like going through all the examples.

You're right, I meant to say that B implies A, not to say that A implies B. However, that is still equivalent to (B || ~A) so the rest, and the conclusion, still follow.
