Shipping calculation

Hello, I have problem on shipping calculation I have created the static shipping address by hidden values

<input type="hidden" name="ship_to_different_address" value="1">
<input type="hidden" name="shipping_first_name" id="shipping_first_name" value="Test First Name">
<input type="hidden" name="shipping_last_name" id="shipping_last_name" value="Test Last Name">
<input type="hidden" name="shipping_company" id="shipping_company" value="Test company">
<input type="hidden" name="shipping_address_1" id="shipping_address_1" value="Test address">
<input type="hidden" name="shipping_city" id="shipping_city" value="Test">
<input type="hidden" name="shipping_postcode" id="shipping_postcode" value="10001">
<input type="hidden" name="shipping_state" id="shipping_state" value="NY">
<input type="hidden" name="shipping_country" id="shipping_country" value="US">

While getting data in class-wc-tax.php $location = WC()->customer->get_taxable_address(); i got only country and not stored in `woocommerce_sessions’ table. Please Advice
