Random weed stock appeared in my portfolio today and I can’t sell it nor do I know where I came from. CBDW

Stock ticker CBDW, a weed stock under the company 1606 corp appeared in my portfolio sometime this month. I checked my buy history and I see nothing. I can barely find anything about it on google. I do have “SING” stock and it says it might be related. Everytime I try to sell the CBDW stock on TD Ameritrade it tells me “error committing trade- these shares are currently non negotiable- these shares may result in oversold/overbought position on your account”

I’m pissed about this because I’m not allowed to have any weed stock because of the job I have.
