Let me clear up the confusion for you, @travelingisawesome.
When you connect your online bank account in QuickBooks Online, the program automatically downloads the last 90 days of transactions recorded by your bank. However, these transactions aren’t in the program just yet.
Once they're in the Bank Feed, you’ll need to categorize these transactions. This way, you can make sure that they're recorded to the correct accounts. You can assign, categorize, edit, and add your downloaded banking transactions.
Let me know if there’s anything else I can help you with. Take care.
