Thank you for your new question.
While you have a handgun permit and carry it wherever permissible by law, if the house is your parent's house they have a legal right to forbid you from coming into their home with a firearm, even if you have a permit.
It is their private residence and you have to honor the owner of the private residence's wishes whether you have a carry permit or not. Thus, it is well within your parent's rights to tell you this and they can call the police and have you thrown out or even arrested for trespassing for coming onto their property with your gun after being told not to do so and for refusing to leave.
