I received 1099-NEC for the work I have done for a civic organization, basically a stipend. Can I list travel expenses to participate in the mtg/activities for this org?

I saw the answers in the community that I should check off 'hobby/sporadic activities' for this 1099-NEC.  Can I list as business expenses the travel expenses (air freights, toll and gasoline) I paid for the meetings & activities I participated in for this organization?
