Hi,welcome to the Community Hello64
Can we confirm when you say your credit card is a positive figure do you owe money on your credit card or are you in credit on it?As the credit card is a liability to the business if you do owe money on the card it will show as you owe money in QB. That amount owed would reduce as payments were paid off the card.
Could you provide a screen shot of the credit card account history(accounting>chart of accounts>account history) and we can check it is set up okay.You can black out anything you do not want to be seen.
