The expression "while you're/I'm at it" is used when someone is already doing a task, but they can also do another task at the same time. It's usually used to suggest doing an additional task that is related to the one currently being done. For example, if someone is already cleaning the kitchen, you might say "while you're at it, could you also clean the fridge?" It can also be used to suggest doing something that is not related to the current task, but needs to be done.
