I've been confused about TDP as well, while buying the parts to upgrade to an AM4. I see 65W TDP on a Ryzen 2700 and 105W on a 2700x... figuring I should see a similar number (or maximum TDP) on the mobo (which I can remember seeing when I first starting looking at upgrading a year ago.
For the first week or so, while looking for a motherboard, I was tracking my brain trying to find TDP numbers on different mobo's. After no success I ended up getting an MSI B450 Gaming Carbon Pro and a Ryzen 2700, figuring 65W was safe. But after posting and getting answers on here I'm sending it back and a 2700x is already on its way (before it's asked I didn't go 3700 because I'm not gaming but video editing and CAD).
So yes, it's confusing for newbies like me- some products with TDP and similar products without! Thankfully this forum filled with knowledgeable people is here or who knows what I would have ended up with!
