Hi,

I understand how it feels when the given solution isn't working.

As Fiat Kux - ASIA shared above, you'll need to convert the IIF files to a CSV or XLS format. From there, import them into your QuickBooks Online account.

On the other hand, the ability to import directly to Turbo Tax is unavailable in QuickBooks Online. You'll need to export the QBO data to QuickBooks Desktop and then import it into Turbo Tax.

If you don't have your own QuickBooks Desktop account yet, you can download the free trial of QBDT.

Once finished, downloading the product. You'll need to export the data to QBDT. From there, you can start moving your QBDT tax information to TurboTax.

For the detailed steps to import QuickBooks data to TurboTax, you can refer to this article: How do I import QuickBooks data into TurboTax Business?

Feel free to get back if you have a hard time with the export process.
