I have a critical issue with my Bank of America connection. QuickBooks automatically synced my accounts, but it incorrectly merged data from debit and credit cards

It doesn't work that way.  You can't just request that kind of help here.  You have to actually contact QB.  

Use the Help (The question mark at the top of your QBO Page) to start a chat or request a call. 

Hello Krukegor-a, I understand how concerning it is to see transactions from your debit card incorrectly appearing in your credit card ledger.

To ensure all your requests are fully addressed. I suggest reaching out to our QuickBooks phone support team directly to take a closer look at the connection between your accounts.

You can do so by navigating to the Help section, selecting the Search tab, and typing "contact support." Click Contact Us, choose your preferred method, and follow the on-screen instructions to connect with a representative.
