Welcome to the Forum from the west side of the state!
I don't see that model number listed for 2020, however, on our TT and many others, the fresh water tank drain and low point drains are all labeled the same with stickers on the side of the trailer as "LOW POINT DRAIN". Look on the floor inside cabinets or under drawers for two lines with a valve on each one. Those will be the plumbing low point drain valves. Underneath there will be either a red and a blue pipe sticking down, or two white ones like on ours that are side by side.
Take a look and let us know what you find, or not. They will be there somewhere.
If you're going to "regret it in the morning", sleep until noon.
