Self Employed am I a material participant?

Hi, I am retired and just started a Marketing Research Contracting Service in April 2019.  I did 558 hours of work during the year for 2 companies.  I got a 1099 and am not an employee.  I am not a decision maker and take direction from an employee of the companies.   I have no involvement in the business other than conducting marketing research for them.  For Sch. C purposes am I a material participant or not?  Thanks
