Why has Intuit not made it possible for QB online to link with Turbotax?

Hi there, @goldeaglepropert. 

The option to link QuickBooks Online (QBO) directly to Turbo tax is unavailable. To move your data, it should be installed on the same local drive as TurboTax (not networked) and needs to be registered. That said, you'll have to transfer your online company files to QuickBooks Desktop (QBDT) before importing them to TurboTax. 

Once ready, you can follow the steps in this article to move the data: Move your QuickBooks Online data to QuickBooks Desktop.

After that, your next step is to export the data to QBDT. Then, move them to TurboTax.

For more details please read this article: How do I import QuickBooks data into TurboTax Business?. 

I'll include this article to use as a reference when moving your data from QBO to QBDT: Learn how features and data move from QuickBooks Online to QuickBooks Desktop.

I'm just around the corner to provide additional help if you have additional concerns in managing your account. Have a good one and stay safe.
