Business & farm

I'm trying to assist my son.  He and his partner had a rolled ice cream business that operating in 2017 and 2018.  He and his partner found jobs in their perspective fields.  It was determined in March or April of 2019 that they would not continue in the business, although they hadn't operated since December 2018.   I'm just trying to get the final 1065 filed properly.

 

I am a CPA but spent my entire career in not-for-profit healthcare.  I'm truly a novice in business tax.
