Hi there, Christine171.

Thank you for visiting the QuickBooks Community. I'll share how accounts work in QuickBooks Desktop. I also provide troubleshooting steps to ensure you can import your data without errors and achieve your goal smoothly.

Since you've mentioned IIF, it seems you're trying to import payroll data from QuickBooks Online to QuickBooks Desktop. Please know that the error you received means the account type of the account you selected on the line is different from what's in your chart of accounts (COA). In this case, I suggest making sure the account indicated in that line have the same type of account that is already in QuickBooks COA.

If the error persists or other messages are found, you will see the number of lists and transactions that failed and were successfully imported. QuickBooks creates a new .IIF file with error information for unsuccessful records, and you then have three options to move forward. You can open this article to learn more about the procedure and how to perform the process: Improved IIF Import in QuickBooks 2019 and later.

If the problem continues to occur, please know that Intuit does not provide technical support for the import and export of IIF files. If you use your IIF file with a third-party program, you can contact the app's technical support for additional assistance in resolving the error. If you created the file on your own, I recommend reaching out an IT professional for more information on how to import your .iif payroll file without issue.

Lastly, you may refer to this article to view some lists and transaction types you can import into QuickBooks: Import and export data in QuickBooks Desktop.
