        $this->_totals['shipping'] = new \Magento\Framework\DataObject(
            [
                'code' => 'shipping',
                'field' => 'shipping_amount',
                //'value' => $this->getSource()->getShippingAmount(),
                'value' => 'TBD',
                'label' => __('Shipping & Handling'),
            ]

You can override this file in your custom theme.

vendor/magento/module-sales/view/frontend/templates/order/totals.phtml

here

app/design/frontend/Vendor/Theme/Magento_Sales/view/frontend/templates/order/totals.phtml

And update content like this ..

<?php
/**
 * Copyright © Magento, Inc. All rights reserved.
 * See COPYING.txt for license details.
 */

/**
 * @var $block \Magento\Sales\Block\Order\Totals
 * @see \Magento\Sales\Block\Order\Totals
 */
?>
<?php foreach ($block->getTotals() as $_code => $_total) : ?>
    <?php if ($_total->getBlockName()) : ?>
        <?= $block->getChildHtml($_total->getBlockName(), false) ?>
    <?php else :?>
    <tr class="<?= $block->escapeHtmlAttr($_code) ?>">
        <th <?= /* @noEscape */ $block->getLabelProperties() ?> scope="row">
            <?php if ($_total->getStrong()) : ?>
                <strong><?= $block->escapeHtml($_total->getLabel()) ?></strong>
            <?php else : ?>
                <?= $block->escapeHtml($_total->getLabel()) ?>
            <?php endif ?>
        </th>
        <?php if($_code == 'shipping'): ?>
            <td <?= /* @noEscape */ $block->getValueProperties() ?> data-th="<?= $block->escapeHtmlAttr($_total->getLabel()) ?>">
                <?php echo "TBD"; ?>
            </td>
        <?php else: ?>
            <td <?= /* @noEscape */ $block->getValueProperties() ?> data-th="<?= $block->escapeHtmlAttr($_total->getLabel()) ?>">
                <?php if ($_total->getStrong()) : ?>
                    <strong><?= /* @noEscape */ $block->formatValue($_total) ?></strong>
                <?php else : ?>
                    <?= /* @noEscape */ $block->formatValue($_total) ?>
                <?php endif?>
            </td>
        <?php endif; ?>
    </tr>
    <?php endif; ?>
<?php endforeach?>

Hope this will help you!
