Turbo tax thinks I have a mortgage so I put "none" in the lender. Now it wants my 1098 information. How do I fix this?

You'll need to delete form 1098 which is in your tax return.

To delete it, please follow these steps:

1. In TurboTax Online, open your return
2. In the left-hand column, locate Tax Tools, click on the drop-down arrow then click on Tools
3. On the Tools Center  page, click on Delete a form 
4. A list of forms will appear. Locate form 1098 and click Delete next to it.
5. On the next screen, click Delete Form
