I just saw a commercial for that Lincon logs show, what channel is that on, since in the commercial, they give you no idea what channel they are on. another one I need is the channel UFO Cowboys is on, again no info in the commercial
Both are Roku originals and can be found on The Roku Channel. Just search within the app.
From watching the video in your other posting (https://community.roku.com/t5/Channels-viewing/Why-am-I-seeing-comercials-for-channels-I-cannot-find...), the commercials you are seeing are for shows that are on the Roku Channel via on-demand. (Roku Originals and on-demand content). These are not always available via the Roku Channel Live TV/linear channels (ie. no channel number).
Do a Search for these programs from the Home Screen "Search" feature on the left side menu, or launch the Roku Channel (not the Live TV guide) and do a search for these shows from within there, as mentioned by @renojim . You will find them available as free on-demand content.
