As noted in a comment, most major calculus textbooks at this time (or more generally: almost anything in the standard undergraduate track, at least freshman-sophomore years) comes with slideshow presentations for the instructor. It's a very common use-case, and one of the principal value-add selling points for textbook publishers these days. It's likely you'll need an instructor account at the publisher's website; ask your publisher textbook sales contact.
That said, to date, I haven't personally seen any that were grade-A "well made". In my experience, I have to commit to revising/editing/upgrading/rewriting them on an ongoing basis, to tune them to my specific course and stylistic focus. Maybe all instructors are too idiosyncratic to fully accept another person's slide organization; but it can be a strategically smart way to get started (esp. if you've received a lot of big new preps at once, and/or you need to focus on your research).
Chris Cunningham's suggestion to ask around at your institution is a good one, of course. I'm the point person at my department for resources like that, and I consider it a good sign of planning and professionalism when people ask. It's probably less likely for slides to be in use/available by traditional math faculty -- but I have friends in other disciplines for whom using department-provided slides is mandatory, so you should check to be sure.
Finally, as one example, the free OpenStax calculus textbooks likewise have instructor slide decks available for free. Again, you'll need to make an instructor account to access them. See the page below and search for "PowerPoint Slides":
