iPhone texts going to Messages instead of Android

I have never owned an iPhone but do have a Mac laptop. But my wife and two daughters all have iPhones and texting between them and my Pixel 6 has been fine up until a couple months ago.

All of a sudden, my youngest daugther's phone (iPhone 12 I think) won't send texts to my Pixel. I can send her texts just fine but when she replies or tries to text me they either go to the messages app on my Macbook (which I sometimes use to text her) or her phone tells her the text can't be sent. I've created 2 separate contacts on her phone for me, one for the Message app with no phone number, and one for my cell phone. But even if I text her from my phen and she replies, it will still sometimes go to messages but never back to my phone.

My wife and other daughter both have iPhone 13s and this hasn't been a problem for them. We're on T-Mobile
