Limit Int/points on 1098. Somewhat complicated situation

[thnguyenmow]

Hi everyone. I was hoping to get some help here.  I'm renting 20% of my house and TurboTax calculated the mortgage tax deduction for my rental and allocated the rest as a mortgage deduction on the personal primary residence. The complication is that the average mortgage balance is greater than $750k limit. TurboTax automatically allocate the 80% of the entire mortgage interest amount to primary residence deduction, I need to limit this to follow IRS guidance. However, under "deduction" section the automatic allocation couldn't be changed. I am using TurboTax online.  As a result I'm having "Limit Int/points on 1098" error that I tried to enter following to no avail:

1. 0

2. Limited amount

3. Blank

4. Negative amount to bring the line transferred from Schedule E down to the limit

Still kicking errors. 

Thanks

Instead of allowing TurboTax to do the math for you, select 'No' and then enter the fractional components for the part of the home you rent out. You do the math in other words. 

Then enter the remaining fractional share on the Schedule A side. Do take into account the mortgage interest cap in both places. So 20% and 80% of your interest on the $750k limit.

Thank you for a response. I'm OK with doing it manually just struggling to figure out where to click to switch that off in the software and how to enter Mortgage interest for partial rental without having it automatically allocated. 

Thanks again

Go back to the property profile section. You'll continue through a few screens to get to the 'Let us calculate your expense deductions for you' page. Select 'No' and proceed with the following screens.
