Why does Lighthouse give me a different accessibility score?

                   <form>
                <fieldset>
                    <legend>Delivery Information</legend>
                    <p class="hint">* - required field</p>
                    <label for "name">Your Name *</label>
                    <input type="text" id="name" name="user-name">
                    <label for "email">Your email *</label>
                    <input type="text" id="email" name="user-email">
                    <p class="hint">Receipt will be sent to this address.</p>
                    <label for "address1">Street address *</label>
                    <input type="text" id="address1" name="user-address1">
                    <label for "address2">Apartment/ Office Number *</label>
                    <input type="text" id="address2" name="user-zip">
                    <label for "zip">Zip Code *</label>
                    <input type="text" id="zip" name="user-zip">
                    <p class="hint">City and state will be looked up from Zip Code.</p>
                    <label for "tel">Phone *</label>
                    <input type="text" id="tel" name="user-phone">
                    <p class="hint">No Phone? Include alternative contact below.</p>
                    <textarea id="delivery-instructions"
                    name="user-delivery-instructions"></textarea>
                    <button type="submit">Continue to Billing</button>
            </form>
