Brand new..needs help

..hello everyone..I have no clue what I’m doing or where exactly I am..I have the app Ottplayer on my Samsung smart tv and did a search for IPTV links and Bam, I ended up here..I have read a lot on ur forum and sorta get it. I have actually added a few lists but I must say, not good ones..keeps buffering and really not many USA channels..which I need because I live smack in the middle. I would appreciate greatly if someone could hit me up with a working link. I have already attempted all that have been visible to me before becoming a member. Thank u for ur time and I am deeply sorry if I have posted where I shouldn’t . thanks again.
