In Pure there are multiple ways to enter a contribution to a conference. Did you bring a written contribution (e.g. paper, abstract, poster)? Please add the contribution as Research output. If you've presented at a conference, this should be entered in Pure as an Activity > Talk and presentation. If you attended a conference (visitor) or contributed in the organization of a conference this should be entered in Pure as an Activity > Organising and attending an event.

More detailed instructions on how to add a conference contribution to Pure can be found in the flowchart ‘Adding conference contributions to Pure’.
