Welcome to the Community, @Tamar9. I’m here to provide insights and assist you with banking concerns in QuickBooks Online (QBO).

If the Expense is downloaded from your bank, click Find Match to locate those two entries. You'll be able to match with different vendors as well. Just make sure the total of these transactions equals the expense.

Let me show you how:

1. Go to the Banking page and select the account where the expense is downloaded.
2. Click the entry to expand it, then choose Find Match.
3. On the Match transactions page, select the Expenses you've entered in QuickBooks.
4. You can also choose Show to open other transactions.
5. Click Save.

If the expense is manually recorded, ensure it is accounted for under Accounts Payable (A/P).

Here's how:

1. Click the New (+) icon on the menu page. Under Vendors, select Expense.
2. Locate the expense you've entered.
3. Choose a category for this expense. Under Category, select the Accounts Payable (A/P) from the Chart of Accounts.
4. Please provide the amount of the expense in the Amount field.
5. Once you've entered all the needed information, click Save and New to save this expense and start another one, or Save and Close if you’re done creating expenses.

When you are done, please link it to the Bill through Pay Bills so that it can be applied as credit.

I've added this screenshot as a reference.
