$largeprofile = [math]::Round(($largeprofile/1MB),2) + "MB"
if($largeprofile -lt 20){Continue}
$object = New-Object -TypeName PSObject

You will have to add the parameter -Force to Get-ChildItem when you are Recursing the directory. From the docs Get-ChildItem the -Force parameter:
Allows the cmdlet to get items that cannot otherwise not be accessed
by the user, such as hidden or system files.
Additionally, you will want to add -ErrorAction SilentlyContinue so you don't get flooded with Access Denied errors. These changes makes your code look like this:
$profiles = Get-ChildItem C:\Users | ?{Test-path C:\Users\$_\NTUSER.DAT} | Select -ExpandProperty Name
foreach($profile in $profiles)
{
$largeprofile = Get-ChildItem C:\Users\$profile -Recurse -Force -ErrorAction SilentlyContinue | Measure-Object -Sum length | Select -ExpandProperty Sum
$largeprofile = [math]::Round(($largeprofile/1MB),2) + "MB"
if($largeprofile -lt 20){Continue}
$object = New-Object -TypeName PSObject
$object | Add-Member -MemberType NoteProperty -Name Name -Value $profile
$object | Add-Member -MemberType NoteProperty -Name "Size(MB)" -Value $largeprofile
($object | fl | Out-String).Trim();Write-Output "`n"
}
