I got billed from QuickBooks Support For a bug in the software

Hi there, @BubblesOwner.

Let me step in and help you with your concern. The amount of the cost column should be in two decimal places since it based on the cost you set up in the item. Also, once you change the item cost in the cost column the amount column will automatically be updated to the total item amount. 

In case you'll need help entering credit card charges, you can follow these steps:

1. Go to the Banking menu, select the Enter Credit Card Charges tab.
2. Click the Credit Card drop-down, then choose the appropriate account.
3. Purchase/Charge should be automatically selected. If you want to record a credit or refund you received through the credit card, select the Refund/Credit instead.
4. Click the Purchased From drop-down and select the vendor.
5. Make sure the date is correct.
6. (Optional) Enter a memo explaining the charge (or refund).
7. Go to Expenses or Items tab and enter the expenses/items you want to track.
8. Select Save Close.
