Form 1065 Schedule K-1 Box 20 Code AN - Farming and fishing business

[BradyJB4449]

I have a schedule K-1 that has a box 20 Code AN referring to a statement.  On the statement is:

AN  Gross farming Income . . . . . . . $x

AN Total Farming Deductions  . . . . $y

TurboTax desktop allows only one amount when selecting Code AN.

Should I right click on the AN amount field and select add supporting details and then add the two values to the supporting details, with the Income $x being positive and the deductions $y being entered as negative.  This would result in one value for AN = income - deductions.

Is that an acceptable approach?
