Welcome to the Community, @jacobsn66.

I'd be delighted to share with you a link that was already given by MaulikH about IIF Overview: import kit, sample files, and headers. Please review the article before using this guide: journal.iif.

This way, you can upload your excel entries to QuickBooks Desktop 2020 seamlessly by following the steps above.

For more details in importing and exporting IIF files, you can refer to this article: Export, import, and edit IIF files.

Additionally, reference this article if you need guidance in importing and exporting data in QuickBooks Desktop: Import and export data in QuickBooks Desktop.

You can always leave a message if you have more questions. I'll keep my notifications. Cheers!
