You may try the following if you don't want to change your current data structure of
view file.

view

public function get_term_level($id)
{
// $terms = Term::find($id);
$terms = Term::with('level')->where('id','=',$id)->get();
if ($terms->count() === 0) {
return redirect()->to('/mypage');
}

return view('term_level.index', compact('terms'));
}


if(!$terms = Term::.....

Inside your method get_term_level you could to the following

get_term_level

public function get_term_level($id)
{
$terms = Term::with('level')->where('id','=',$id)->get();

if($terms->isEmpty()) {
return redirect()->to('/mypage');
}

return view('term_level.index',compact('terms'));
}


You could just have a route that redirects

Route::get('term/test', 'ListController@redirectHereFunction');
Route::get('term/test/{id}', 'ListController@get_term_level');
