Thanks for joining us here in the Community, @Raza Q.

If you already tried performing the steps presented by my peers above, and the issue persists, I recommend contacting our Customer Care Team. They have the tools like the screen-sharing session that can help narrow down this issue.

To reach them:

1. Go to the Help menu.
2. Choose QuickBooks Desktop Help.
3. Tap the Contact us button.

I'm also adding here some links that you can check out about importing and exporting data in QuickBooks Desktop:

• IIF Overview: import kit, sample files, and headers
• Export, import, and edit IIF files

I'm always up to help if there's anything else you need, Raza. Just reach out to me here, and well take it from there. Have a great night!
