How should I enter credit card charges

I'd be glad to help you enter credit card charges, Slahaie.

In QuickBooks Online (QBO), you can create an expense transaction or expenses when entering credit card charges. Then, you'll have to select a category to post the amount individually.

Here's how:

1. Go to the + New icon and then choose Expense.
2. Choose the credit card account under the Payment Account drop-down menu.
3. Select the credit card type under the Payment method drop-down list.
4. Fill in the other necessary information.
5. Once done, click on Save and Close.

For reference, check this article: Enter and Manage Expenses.

In addition, I recommend reconciling your account in QuickBooks to ensure your bank and credit card statements match. 

I'll also add this article that contains detailed information about recording invoice payments: Record invoice payments in QuickBooks Online
