How do you deal with feeling like your underperforming/not doing enough at work?

Hey guys,

So I (22M) am doing an entry level clerical role at a school district. Overall work has been good and I haven't really been in trouble for anything major. However I feel like I get my work done and then I find myself looking at my coworkers and they seem to be finishing their part of the project. I've also noticed that my supervisors will often ask them to do data pulls for students and stuff while they kind of ignore me. I addressed this to one of my coworkers and he said to just ask questions, but what questions can I ask if I don't have any to share? Also since Im part of a team thats supposed to help fix any issues regarding student data, I will try to look through any errors but then I end up getting stuck on something that would have to be addressed through our weekly support meetings with the database support team. Idk if this is considered imposter syndrome but it feels like it. I just don't want to get my work done and then look like Im just on my phone or doing nothing at all. It also doesn't help that Im supposed to get a review done this week for my performance since I joined in June. Have any of you guys felt this way?
