Question

I have tried but didn't got anything related to this.

$parent_categories = get_categories($parent_args); 

foreach($parent_categories as $parent_category){ ?>
<?php //create main headings for other categories other than Uncategorized.
if($parent_category->name!="Uncategorized"){
    $category_label = "By ";
    echo '<br>';
    echo '<h5>'.$category_label.''.$parent_category->name.'</h5>';

    //fetch the parent category's id
    $firstchild_args['parent'] = $parent_category->term_id;
    $firstchild_categories = get_categories($firstchild_args);

    //fetch all the first level children categories
    //fetch all the first level children categories
        $limit=15; // Set Child limit here
        $counter=0; 

        foreach($firstchild_categories as $firstchild_category){
        if($counter<$limit){
        $output = "";
        $output = $output."<div class=\"checkboxes-group\">";
        $output = $output."    <input type=\"checkbox\"  value=".$firstchild_category->slug." class=\"js-filter-checkbox\" name=\"category[]\" id=".$firstchild_category->cat_ID.">
        <span style='font-size: 17px; color: #404040;'>".$firstchild_category->name;
        $output = $output."</div>"; 
        echo $output;  
        $output = $output."</form>"; 
                $counter++;
        }
        }

}
} ?>

Before printing anything you should first fetch all child category, Then you cant check child item is empty or not with empty function and then continue the current loop to skip this category, So you can add if(empty($firstchild_categories)) continue and your could can be like this

<?php
$parent_categories = get_categories($parent_args);
$limit   = 15; // Set Child limit here
$counter = 0;

foreach ($parent_categories as $parent_category) {
 //create main headings for other categories other than Uncategorized.
    if ($parent_category->name != "Uncategorized") {


        //fetch the parent category's id
        $firstchild_args['parent'] = $parent_category->term_id;
        $firstchild_categories     = get_categories($firstchild_args);

        if( empty($firstchild_categories) )
           continue;

        if($counter > $limit)
           break;
        $counter++;
        $category_label = "By ";
        echo '<br>';
        echo '<h5>' . $category_label . '' . $parent_category->name . '</h5>';

        //fetch all the first level children categories
        //fetch all the first level children categories


        foreach ($firstchild_categories as $firstchild_category) {

                $output = "";
                $output = $output . "<div class=\"checkboxes-group\">";
                $output = $output . "    <input type=\"checkbox\"  value=" . $firstchild_category->slug . " class=\"js-filter-checkbox\" name=\"category[]\" id=" . $firstchild_category->cat_ID . ">
        <span style='font-size: 17px; color: #404040;'>" . $firstchild_category->name;
                $output = $output . "</div>";
                echo $output;
                $output = $output . "</form>";

        }

    }
}
?>
