Why my quickbook cannot use import function when create a journal?

Hi there, fongyee.

Currently, there's no option to use the import icon/function when creating journal entries.

However, I suggest visiting our App menu inside QuickBooks and look for a third-party app that lets you import the journal entries. QuickBooks connects to hundreds of different apps that you can choose from.

Here's how:

1. Click Apps in the left navigation menu.
2. Click the Browse Category drop-down menu, select Data Sync.
3. Select the app you want to integrate.
4. Click Get App Now and complete the following on-screen instructions.

I also recommend going to this site: https://quickbooks.intuit.com/blog/. From there, you can get the latest updates as well other references while working in QuickBooks.

If you want to apply a journal entry as a credit to your customer's open invoice, please check this article to see the steps: How to apply a journal entry credit to an invoice.
