Answer – the correct formulation is…

      'meta_query' => array(
        array(
          'key'     => 'Topic',
          'value'   => "12057",
          'compare' => 'LIKE'
        )
      )

In full:

    $args = array(
      'taxonomy' => 'event',
      // 'order' => 'ASC',
      'hide_empty' => false,
      'hierarchical' => true,
      // 'parent' => 0,

      'meta_query' => array(
        array(
          'key'     => 'Topic',
          'value'   => "12057",
          'compare' => 'LIKE'
        )
      )

    );

    $events = get_terms( $args );

Specifically, it seems 'compare' => 'LIKE' needs to be present.

Initially, I had thought the solution was to use double quotes on the value, which I inferred from @hube2‘s response to another question.

But actually it works with single or double. The clincher is the present of 'compare' => 'LIKE'.
