Because of a death my husband didn't receive his W2 from 2022 until 12/19/23. I filed an extension & already paid what we owed at the time. What do I do now?

It was my mom & step-dad's business. He passed. My mom has Alzheimer & my brother is living with her. It's been a mess. He just got guardianship & we just got to the 2022 taxes for everyone. I just want to file with this last W2 before we get more penalties. Can someone please tell me what to do now. I filed threw turbortax for years now
