Upon adding your site, you will want to choose Crawl > Sitemaps in the left column. Here, you will click Add/Test Sitemap in the top right corner. You will want to enter sitemap.xml in the box that appears when clicking this link.
After choosing "Submit Sitemap", you should see it appear in your list of sitemaps. This is all you need to officially submit your sitemap to Google.
