It's very easy to get distracted as a developer on something that adds little to no value. You will do this repeatedly throughout your career. Try not to :)

It may also depend how much you're micromanaged vs. picking your own path. Sounds like you're saying none of your work is self directed, and you don't participate in design decisions yet?

Anyway, even if you don't have much say there's still ways to direct your work. You can push back against whatever is demanding the low value work.
