Yes, it is possible, @Cosh.
You can match multiple journal entries to a single bank transaction. You'll just have to click the Match radio button so QuickBooks will locate the journal entries. Let me guide you through the process.
- Sign in to your QuickBooks Online (QBO) account.
- Click Transactions/Banking from the left menu.
- Select the appropriate bank account, then go to the For Review tab.
- Choose the downloaded transaction to expand the view.
- Tick the Match radio button.
- In the Select transactions to match section, put a checkmark on the journal entries you want to match.
- Click Match once done.

After matching all your journal entries, you may proceed with reconciling accounts. This is to ensure your balance matches your real-life bank account.
