There is nothing to worry about. Since 1099 is issued to those who are not employees, then it is considered self-employment. All the questions which you saw were part of Schedule C which all independent contractors need to fill and submit. Since you are filing a 1099-nec, you are required to answer those questions so that you can deduct any expenses which you had while performing the work and so that you can pay self-employment tax on the earnings.
