I need to update the post query? [closed]

You should use tax_query.

$args = 
  [
    'posts_per_page' => 10,
    'post_type'  => 'post',
    'post_status' => 'publish'
    'tax_query' => array(
        array(
            'taxonomy' => 'state',
            'field'    => 'slug',
            'terms'    => 'minnesota', // lowercase m
        ),
  ];
