We need to take a deeper look at this. In order to do this, we need you to provide us with a diagnostic file which is a copy of your tax return that has all of your personal information removed. You can send one to us by following the directions below:

Open your return.
Locate the Tax Tools on the left-hand side of the screen.
A drop-down will appear. select Tools
On the pop-up screen, click on Share my file with agent.
This will generate a message that a diagnostic file gets sanitized and transmitted to us.
Please provide the Token Number that was generated in the response.

TurboTax Desktop/Download Versions:

Open your return.
Click the Online tab in the black bar across the top of TurboTax and select Send Tax File to Agent
This will generate a message that a diagnostic copy will be created. Click on OK and the tax file will be sanitized and transmitted to us.
Please provide the Token Number that was generated in the response.
