I know it can be challenging when you encounter issues while importing an IIF file, Christine171. I'll provide additional troubleshooting steps to help you sort out this issue.

If you haven't tried running the Verify and Rebuild data tools to get this resolved, we can perform this to verify and resolve the most commonly known data issues within your company file. First, please ensure that your QuickBooks Desktop is up to date. Here's how to verify data:

1. Navigate to the File menu.
2. Choose Utilities, then select Verify Data.
3. Click OK when you see the message, QuickBooks detected no problem with your data.
4. If Verify finds an issue with your data, you'll be prompted to Rebuild Now or View Errors.
5. Click Close or View Errors and take note of the specific error message.

Next, here's how to rebuild the data:

1. Go to the File menu.
2. Choose Utilities, then select Rebuild Data.
3. Click OK if you receive a prompt to back up your company file.
4. Click OK when you get the message, Rebuild has completed and proceed to the next step.
5. Run Rebuild Data again to make sure there are no errors.

If the issue persists, I recommend contacting our Technical Support Team. I understand that you've already reached out to them. However, it would be best to contact them again. They have the tools to look into your account and verify what caused this issue.
