I bought a house with my sister and don’t have the 1098 or whatever it’s called. Do I claim the house or does she?

[JotikaT2 · Accepted solution]

It depends.

You will both need to discuss it to determine if she is taking the deduction, or if you are going to split the deduction.  

If you decide to split the mortgage interest deduction, you can do so as follows.

1. Go into the Federal program.
2. Select "Deductions & Credits"
3. Select "Mortgage Interest and Refinancing (Form 1098)

Make sure you answer the questions regarding the 1098 form and input the information as prompted.
