Limiting a Macro applied to only 1 worksheet in a file

This script works well for my need, hiding specific columns, unfortunately it also hides columns in other worksheets in the same file. can anyone help me keep the macro focused on only one worksheet? The Sheet name i need it to work on is called "Member Data"

Sub UNCheck_Hide_Columns()
        
    Dim sh As Worksheet
    Application.ScreenUpdating = False
    
    For Each sh In Sheets
        On Error Resume Next
        sh.CheckBoxes.Value = False
        On Error GoTo 0
    Next
