I added simple product with options programmatically into cart using this code.

namespace VendorExtensionControllerCustomer;

class Myclass extends MagentoFrameworkAppActionAction

 protected $messageManager;
 protected $custsession;
 protected $_responseFactory;
 protected $_url;
 protected $_appRequestInterface;

 public function __construct(MagentoFrameworkAppActionContext $context, 
 MagentoCustomerModelSession $custsession,
 MagentoFrameworkAppResponseFactory $responseFactory,
 MagentoFrameworkUrlInterface $url,
 MagentoFrameworkAppRequestInterface $appRequestInterface,
 MagentoFrameworkMessageManagerInterface $messageManager)
 
 $this->custsession = $custsession;
 $this->_responseFactory = $responseFactory;
 $this->_url = $url;
 $this->_appRequestInterface = $appRequestInterface;
 $this->messageManager = $messageManager;
 parent::__construct($context);
 

 public function execute()
 
 if($this->custsession->isLoggedIn())
 
 try
 
 $params = [
 'product' => 12,
 'selected_configurable_option' => NULL,
 'related_product' => NULL, 
 'options' => [
 3 => 8,
 ],
 'qty' => 2
 ];

 $product = $om->create('MagentoCatalogModelProduct')->load(12);
 $mycartp = $om->get('MagentoCheckoutModelCart');
 $mycartp->addProduct($product,$params);
 $mycartp->save();

 $quote = $om->get('MagentoQuoteModelQuote');
 $quote->setTotalsCollectedFlag(false)->collectTotals()->save();

 $checkout = $om->get('MagentoCheckoutModelSession');
 $checkout->getQuote()->collectTotals()->save();

 $message = "Your quote has been successfully added to cart";
 $this->messageManager->addSuccess($message);

 $accUrl = $this->_url->getUrl('checkout/cart/');
 $this->_responseFactory->create()->setRedirect($accUrl)->sendResponse(); 
 exit;

 
 catch(Exception $e)
 
 $this->messageManager->addError($e->getMessage());
 $accUrl = $this->_url->getUrl('extension/controller/mypage');
 $this->_responseFactory->create()->setRedirect($accUrl)->sendResponse(); 
 exit;
 
 
 else
 
 $accUrl = $this->_url->getUrl('customer/account/login');
 $this->_responseFactory->create()->setRedirect($accUrl)->sendResponse(); 
 exit;
 
 

The product sucessfully added to cart with options, but it not show correct subtotal in cart page and mini-cart. See below screen-sort.

One's I click on "Update Shopping Cart" it show correct total. See below screen-sort.

Any one know about this?

Please replace below code with my code :

Replace This :

 $quote = $om->get('MagentoQuoteModelQuote');
 $quote->setTotalsCollectedFlag(false)->collectTotals()->save();

 $checkout = $om->get('MagentoCheckoutModelSession');
 $checkout->getQuote()->collectTotals()->save();

Replace With :

$quoteRepository = $om->get('MagentoQuoteApiCartRepositoryInterface');
$quoteObject = $quoteRepository->get($mycartp->getQuote()->getId());
$quoteObject->setTriggerRecollect(1);
$quoteObject->setIsActive(true);
$quoteObject->collectTotals()->save();

Above code works for me. So please try this one.
