Get your taxes done using TurboTax

I believe it is appearing this way because you are entering the Form 1098 Information in the "Deduction and Credit" section of your Return.

Therefore, you need to revisit that section and delete Form 1098.  The mortgage balance and interest on none of the information should be entered due to the fact that you are claiming partial rent. See the screenshots below. Click on Edit

On the next page, Click Trash.

You will repeat the same step for Property Tax.

Once your Federal Return is fixed you should not have an issue with California since the information should flow correctly.

If you are not able to delete the Mortgage Interest using the Trash, then use the Tool Feature on the Left to delete: See steps below:  Also clear Cache before logging back in by clicking Here.

1. Log in and open your return
2. Click Tax Tools from the left side of the screen
3. Select Tools from the drop-down menu
4. Click the Delete a Form hyperlink click to delete Form 1098
