I'd be glad to help you add the missing transaction to your QuickBooks Online company, OwnerDriverLightHaulage.
You have two options to add a transaction in QuickBooks. First, you can manually import a CSV file from your bank and select a single transaction to upload. Here's how to do that:
- On the left navigation panel, go to Transactions.
- On the Bank transactions tab, head to the Link account dropdown and then Upload from file.
- Upload the file, and then Continue.
- Follow the onscreen steps to map the columns to the correct fields in QuickBooks.
- Tick the missing transaction you like to import. Then, Continue.
- Click Yes, and then Done.
Once the transaction is on your bank feeds, categorise it into the right account.
Alternatively, you can head to the +New button. Then, select Expense so you can record the credit card transaction. I left a screenshot below for your reference.
