I saw this movie in the late 1988-1992. It was in color, English language, movie seen on TV.
This little girl has premonitions of a dead little girl family member. She was insistent on finding out what happens to her but it is a family mystery of this girl that disappeared. She goes to spend a summer with some family members and discovers a skeleton of a little girl under the house. They say that she can now Rest In Peace because she was found.
Sounds like Mystery Mansion.

That is it! I just looked it up! I’ve been searching for that movie for decades. I was only a kid when I saw it.
Excellent! Credit to Drea (AKA faeriegrrl).
