I question if SCH F is the correct form. It might be a SCH C business. If you'll check out Part IV of the SCH F at
https://www.irs.gov/pub/irs-pdf/f1040sf.pdf you'll see it states:
Do not file Schedule F (Form 1040) to report the following.
• Income from providing agricultural services such as soil preparation, veterinary, farm labor, horticultural, or management for a fee or on a contract basis. Instead file Schedule C (Form 1040) or Schedule C-EZ (Form 1040).
• Income from breeding, raising, or caring for dogs, cats, or other pet animals. Instead file Schedule C (Form 1040) or Schedule C-EZ (Form 1040).
• Sales of livestock held for draft, breeding, sport, or dairy purposes. Instead file Form 4797.
So based on that last item, I question if a SCH C will be filed, with Form 4797 to report the sale of business property. Depending on the purpose for which they were raised and sold, I would go with SCH C. Then any taxable profits from the SCH C business can count for retirement contribution.
