Thanks for coming here with your concern, smallbusinesser. Let me share information and help you rectify the issue you're having when importing IIF files.
As shared by my colleagues above, the error you're having triggers the account type you're using on that line is different from the accounts used on the Chart of Accounts (COA). That said, you'll want to ensure the type of account entered has the same account type that is already in your COA. For additional insights, you can refer to this guide to help you import and avoid errors: Improved IIF import in QuickBooks 2019 and later.
If the same error persists after reviewing the account type used, you'll want to consider following the troubleshooting steps provided by my colleague, Kevin_C.
If you're still encountering this issue, I recommend contacting our Customer Care Team. It's best to have them as they're able to pull up and review your account. Also, they'd further provide you with the assistance you need in resolving this.
Furthermore, I'm adding this helpful reference to help you modify and manage your IIF files: Export, import, and edit IIF files.
