Spend time with the code before you ask for help. Try different things, break things locally and understand how the code stands in a bigger system level picture. If you are in a good organization, they will support you breaking things in staging as it will provide them a better picture of code reviews etc. So break things and learn fast. Most importantly, junior software engineers and interns often complain that the work they do is not impactful - it may seem that those around you are doing impactful work (and it might actually be true in a very few cases), but don't let this effect your peace of mind and not let you give your best. Every work you do must show a characteristic of your quality. Engineers must be able to provide anything in their field, at all levels of their stack, regardless of how important they feel their work might be. Always respect your work and be grateful for getting an opportunity for working on it because someone did not get that chance.
