Debugging - length of time

Some people say that debugging can take a few hours, others days depending on the code base (legacy or larger at a bigger tech company). On average, if I am at an earlier stage startup or a mid-size company (or big FAANGMULA), how long should this be?

I feel like I've been wasting a lot more time on debugging for deploying (lots of minor syntax errors and stuff AI may not catch or careless mistakes and other dependency conflicts) than on actual real logic and I feel like it's taking forever. I just want to be sure I'm spending my time well for my projects, since I have so many, and even if this is one of my earlier ones, I'm worried that I'm spending too much time on it, even if my code quality is higher.
