Box 13 for Code K - excess business interest expense needs Form 8990 - HELP!!

Hi,

Turbotax does not provide any help for Form 8990 and I have no clue how to do it. 

I own shares in a publicly traded MLP, called Plains All American Pipeline.

My K-1 for Plains All American Pipeline has Box 13 - with a code K amount of $250.

This is the only K-1 that I have. I am a W-2 employee who does not own a business or have any other business interests. 

I downloaded the Form 8990 from the IRS website and am trying to fill it. I have attached some pictures and was wondering whether what I have filled in makes sense....

 

 

 

 

 

 

The Excess Business Interest Expense of $250 does not seem to appear anywhere except in Schedule A!!

Is this even correct?

If there was no additional information reported in the K-1 statements, I believe the way you have filled out the form is correct.  If they reported any "Current Year Excess Taxable Income", you would enter that in column f of Schedule A.  You might want to go through the Instructions for Form 8990

 

You don't report this on your tax return, but you have to reduce your basis in Plains All American Pipeline (but not before zero) by the amount of the excess business interest.  This could affect non-taxable distributions deemed a return of basis.  If you dispose of your interest in the partnership, you add back to your basis any unused excess interest expense.
