I can think of two ways how you can enter data for journal entries in QuickBooks Desktop, @maxjunerd. 

Let me share with you some information about handling your data.

In QBDT, data entry for JE can be done either manually or in bulk using IIF files. I'll show you the detailed steps:

To add JE manually:

1. Open the Company menu and click on Make General Journal Entries.
2. Fill in the fields to enter your journal entry. 
3. Ensure your debits are equal to your credits once you’re done.
4. Click on Save or Save & Close.

To import IIFs: 

 Note: Before importing the files, make sure to back up your company. This way, you can restore data easily in case you encounter any problems along the way.

1. Log in to your company as an administrator. If Multi-user mode is on, open the File menu, then click on Switch to Single-user Mode.
2. Click on the File menu, then hit Utilities.
3. Choose Import, then click on Import IIF.
4. Choose the IIF file you want to import, then hit Open.
5. Click on OK to confirm.

Additionally, feel free to read about the limitations when importing and exporting IIF.
