Let's fix this banking issue as early as possible, @Gem35. You're in the right place to look for answers.
Happy to share some details about banking feeds work in QuickBooks Online. This way, I can guide you accordingly.
Are you referring to your sub-accounts? If so, you need to know how your bank sends the downloaded transactions before connecting to Online Banking. This way, the data are classified accordingly in QuickBooks.
If the transactions download to one account, tie up only the parent account. Otherwise, you will want to connect the subaccounts. Please be aware that you cannot link a parent account and its sub-accounts. For more details, check out this link: About bank or credit card subaccount setup.
Regarding deposit transactions, QuickBooks will always depend on what your bank shares with us and how they're posted online. With this, I'd recommend contacting your bank. They can review your bank settings and help you from there.
In addition, don't forget to reconcile to make sure they match your bank and credit card statements.

Lastly, may I know your bank's name? So I can review our reports if we have an ongoing investigation. Thus, I can give you accurate solutions.
Drop a line if you're referring to something else or you have follow-up questions about your bank feeds. I'm happy to answer all of your questions. Keep safe, Gem35.
