@DrEH  Well, you actually have more issues than you might be aware of.

As mentioned, all entries in QB are based on double-entry accounting.

This means that, if you know you have one account that you need to correct, you actually have at least two accounts you need to correct; whatever error QB originally made, it did so using at least two different accounts.

The first thing you should focus on is figuring out what else is wrong, and make an entry to correct all of the affected accounts, not just the one you're aware of.

Probably the easiest way would be to go to the actual entries QB screwed up and fix those instead. Assuming QBO actually allows you to do that; I don't use bank feeds or QBO, so I'unno if QBO hardlocks their own entries, or how you'd look that up easily.

@Rainflurry  Thoughts?
