Let me help you link your BofA Master Card to QuickBooks Online.
This happens if you added multiple cards with the same bank in QuickBooks.
Before connecting to Online Banking, you need to identify how your bank sends your downloaded transactions. If they download transactions to only one account, you can connect the parent account. If it downloads to the individual accounts, connect the sub-accounts.
Follow the steps below to connect your card:
1. Click the Gear icon and select Chart of Accounts.
2. Locate the bank account to connect.
3. From the Action column, Click the View Register drop-down and select Connect bank.
4. Follow the prompts to connect your bank account.
