Hi Sue. I'm Greg, an installation specialist and 9 year Windows MVP, here to help you.
See here how to set up screen time limits in MS Family Safety: https://support.microsoft.com/en-us/help/402824...
This thread suggests removing and adding back the account: https://answers.microsoft.com/en-us/windows/for...
If you've already tried that and Family isn't working correctly then what i recommend is contacting the MS Family representative Daniel Strommen at the contacts he gives in another thread here: https://aka.ms/famsafefaq

I hope this helps. Feel free to ask back any questions and let us know how it goes. I will keep working with you until it's resolved.
