Your facts are very limited:
- Whether an activity is deemed sporadic or a trade or business is based on facts and circumstances
- You don't mention how many Zoom meetings you attended
- You don't indicate how you became involved in this project
- You don't mention how much you were paid
- You don't indicate whether this is something you have done in the past or expect to do in the future
- In general, a sporadic activity would be something that does not have a degree of recurrence, continuity, and availability. Where you fit in this spectrum based on the questions above will dictate the answer.
- Always keep in mind, that if the position is gray, the IRS may challenge your position.
