My sister called APS on me...advice?

My older sister called APS on me. She told them I beat up my parents and my son, and that I take control of my parents financially. Two weeks ago my mom went to ER for Altered Mental Status. My sister trying to be sneaky try to get poa over my mom and dad with the help of her lawyer friend. I was given permission by my dad to visit my mom at hospital since only one person was allowed during the entire stay for my mom because of Covid. My sister found out and thought I told the hospital to ban her, so she called APS on me, and my husband. I didn’t make the choice to be the designated visitor, my dad did. She was saying horrible things that we weren’t doing. My sister says she’s going to use her judge friends and lawyer friends to put me in prison. My two sisters and I split care for my mom, but my oldest sister who called never helped my mom, she has diabetes, blind and bed bound. My oldest sister never paid bills the 6 months she lived with us, my parents only took her in because her boyfriend beat her up. She has caused nothing but trouble. She’s 50, why she’s not on her own, now I know. Last year my parents gave their house to my son. They found out and got extremely jealous. They have been begging my mom to put them on the deed but my parents refuse because they are mean to them. My parents recently kicked them out and they left leaving me responsibility of both parents alone. But they cause so much trouble, like sneakily trying to get financial poa telling my dad it’s medical with the help of a lawyer. And over my mom while she was in ICU. When my dad found out it was financial she was so scared, I had to find him an attorney to fix it. My sisters told me my mom was never coming home and they were taking control of the house. But my dad asked my husband to help kick them out, he felt betrayed. Now there’s a case against me and my husband for lots of ugly things including beating my son. I never disrespect my parents, or put fear into them, or hit them or take control of their finances. It’s a real mess, I have to care for my mom who just wants to live the rest of her life in peace at home not in a nursing home. I was going back to school for nursing, but have to put on hold to care for my mom and dad, my dad is a lot more independent but mom is like a newborn. I’m trying my best and now I have this lies told about me, last time she was here the case worker was looking at me like she wanted to make a big deal, I have been honest with her, but who knows what my sister and her attorney told them, she mostly question my husband about the property who has no involvement when my parents gave the house to my son. This is the worst, any advice thank you.
