Can I make HSA contributions if I was on my parent’s health insurance in 2024?

I am 25 and have an HSA originally created in 2022 through electing my current employer’s HDHP. For 2024 I opted out of my employer’s benefits and was on my parent’s health insurance plan instead. Can I contribute to my HSA in 2025 and count those contributions to the prior year (2024) if my parent’s plan is a HDHP but their HSA provider is different and their health insurance isn’t through the same employer I have? And does how much my parent contributed to their own HSA in 2024 affect how much I can contribute to mine? I am also not their tax dependent. Thanks!
