function plus_one_glava_diu_miu_dc ($post_id, $form_data)

// Custom field name
$mmeta_key = "wpcf-glavamiu";

// Get value from parent MIU field
global $post;
$parent_post = $post->ID;
$field_slug = 'miuonline_volshebniki';

$get_results = toolset_get_related_posts( $parent_post, $field_slug, 'parent', 1000, 0, array(), 'post_id','child');
$parent_glavamiu = types_render_field( 'wpcf-glavanastavnika', array( 'item' => $get_results) );

Hello. Thank you for contacting the Toolset support.

As I understand - you have Toolset Form for parent post type and when you submit the form you want to get the specific field value belongs to parent post and assign that field value to child post. If this is true - to What child post you want to assign the field value as child will be many how to know what specific child post is updated with parent custom field value?

Please correct me if I'm wrong and once we clarify the things I will be able to guide you in the right direction.

In addition to that - Could you please send me debug information that will help us to investigate your issue.

You can use the Post relationship API function toolset_get_related_post which is set to return the parent ID value. As you can see with the following Doc:
=> https://toolset.com/documentation/customizing-sites-using-php/post-relationships-api/#toolset_get_related_post

Can you please try to use the following modified hook code:

add_action('cred_save_data', 'plus_one_glava_diu_miu_dc',10,2);
function plus_one_glava_diu_miu_dc ($post_id, $form_data)  {
// Execute for form ID: 123
if ($form_data['id'] == 16709 ) {

// child post Custom field name
$mmeta_key = "wpcf-glavamiu";

$relationship_slug = 'miuonline_volshebniki';

// get parent ID
$parent_id = toolset_get_related_post( $post_id, $relationship_slug,'parent');

// get parent custom field value
$parent_glavamiu = get_post_meta($parent_id ,'wpcf-glavanastavnika',true);

// Finally, update $meta_key for $user_id with $newValue
update_post_meta( $post_id, $mmeta_key, $parent_glavamiu);

}
}
