3. From the QuickBooks account dropdown, choose the sub-account where you want to upload the transactions.

Please note that certain restrictions apply when changing or managing accounts in the Chart of Accounts, including online banking. Therefore, if your main or parent credit card account is already connected to your bank, importing transactions under the sub-account isn't possible. In this case, you'll need to disconnect the main or parent account before importing your transactions under the sub-account.

Here's how:

1. Go to the Banking menu and proceed to the Banking tab.
2. Select the account that needs to be changed to a sub-account.
3. Click the pencil  icon, then select Edit account info.
4. Select the Disconnect this account on save checkbox. 
5. Click Save and Close.
