Checking If a Exists Record

how can check if there is a record? i need to make a condition, which hides a layer if there is a record.

IF the event id exists in the charges table: hide

@if ($cobros->turnos == $event->id)

<h5>Paid Service</h5>

@else
    <div class="input-group mb-4">
  <div class="input-group-prepend">
    <span class="input-group-text">$</span>
  </div>
  <input type="hidden" value="" name="servicio_id">
  <input type="hidden" value="" name="turno_id">
  <input type="text" value="" name="importe" class="form-control col-md-3" aria-label="Amount (to the nearest dollar)">
  <div class="input-group-append">
    <span class="input-group-text"></span>
  </div>
</div>


    </div>
  </div>
  
  </div>

@endif
