Form 1099-MISC use to be used for non-employee compensation but now the Form 1099-NEC is the form for non-employee compensation. However, if Box 2 is the box with a number, it is going to ask you for a Schedule C or Schedule E. The correct form in your case would be Schedule C.
With that said, if you are a car salesman and you are paid based on commissions that is considered as self-employment income for tax purposes. The 1099-MISC should be reported on a Schedule C. You will want to link the 1099-MISC to a Schedule C. You can deduct any expenses related to your work that are not reimbursed to you by the company. Otherwise, all that will be on Schedule C is the commission you received. This income is subject to self-employment taxes.
To fill out the top part of the form, simply complete the type of business - product; you will have to pick a business code for car sales, and the name of the company you can use the company name on your 1099-MISC. The tax ID number can be left blank.
