Would it be acceptable to do the following for Schedule K-1 Box 20 Code AJ step-by-step?

 

(1) Select the code AJ - Excess business loss limitation

(2) For the amount field, right click and add supporting details

(3) Add the aggregate business activity gross income

(3) Subtract the aggregate business activity deductions

 

The above documents both numbers in the supporting details.

Would this be an acceptable method for code AJ?  Are there downsides to doing this?
