This is something you'd really want to talk to your priest about since different parishes and individual spiritual directors have varying takes on it. That said, the official Catholic teaching is that in-person attendance at Sunday mass is expected as part of the precept of the Church - it's not just about watching, it's about being physically present and participating in the community and sacrament. COVID kind of created this grey area where livestreaming became necessary, but now that things are back to normal, the expectation has generally shifted back to in-person attendance.
That doesn't mean you're doing something terrible if you're watching online - a lot of people are juggling similar schedules with work and kids' activities, and the Church recognizes that life happens. But if you're feeling guilty about it, that's probably worth exploring. Some parishes have Saturday evening masses or weekday options that might fit your schedule better than Sunday morning. You could also talk to your priest about your specific situation - they deal with this stuff all the time and might have actual solutions or at least give you clarity on what's expected vs. what's flexible in your particular parish.
The guilt you're feeling suggests you know what the standard is supposed to be, so even just making an effort to get there when you can, or adjusting your schedule even a little bit, might help settle that. But definitely have the conversation with your parish - they're way better equipped to guide you on this than the internet is.
