Two Jobs W4 Question

I’m probably making this more difficult than it needs to be. I’ve had two jobs the last 5-6 years and I’ve never really changed anything on my W4. I’m single with no dependents (so I claim zero non-exempt I think?). Am I good to have it like this on both my W4 forms or am I missing something? Nothing bad has happened yet, and I’m pretty sure since I’m single and claim zero I can’t really do much else. So am I good?
