Commission made on sales while employed (1099-MISC)

My spouse has two 1099-MISC forms for sales commissions/bonuses. One form is from a "partner" of the company for which he's currently employed. The other is from a company who terminated him, but it's commission on sales he made during his actual employment. When I enter the 1099s, TT puts them on Schedule C, but it's not self-employment income. That is, he doesn't have a business, nor was he considered a contractor when he earned the money. How should I file these 1099s?
