Great news, you can link your credit card to your account in QuickBooks Online. In doing so, you'll be able to update it, and it will load in the transactions from the credit card automatically for you. However, if you prefer to do this manually, you can import your transactions using a CSV file. Below I've included the steps to connecting your credit card into QuickBooks.
1. Open the Banking menu, choose your account, and click Add account.
2. Search for your credit card company and hit the enter key on your keyboard.
3. Sign in to your account using your credit card login credentials.
