Deductions & credits

If you are doing this in TurboTax you will take the following steps

 

  1. Enter the 1098
  2. Click through until get to "Let's get some details about this loan" and select whether it was a refinance or HELOC
  3. A drop down will appear, select Yes for the question "Did you use your loan for anything besides paying off the existing loan"
  4. Next select I used some or all of this loan on a different home or on something other than a home
  5. Help Me figure it out
  6. Enter the amount you used on the home and the ending balance of the mortgage
  7. This will do the calculations for you.

As for how you actually do the calculations...

If you used $10,000 of the $30,000 for home improvements and the other $20,000 was for whatever not related to your home, then you would be able to deduct 1/3 of the interest.  (10k/30k=1/3=.333)  so if your interest was $3,000, you would be able to deduct $1,000.
