Class action settlement from a worthless stock, $0 proceeds, that closed tax year 2023. Do I claim monies received,in the Class action, as misc income, or reduce basis for this stock, on sch D, or some other way?

Did you receive a 1099-MISC?  If not, what type of tax document did you receive?  Please clarify so we can assist you.

You are supposed to take schedule D loss on worthless stock in the year it becomes worthless.

If you have not done that and you consider the stock to have become worthless in 2023, you can do that now.

I didn't receive the answer I was looking for. The stock was deem worthless last year, and is in my tax return as such, on my sch D. I received monies from a class action on this stock, last year also, without receiving a 1099 mis.  Do I deduct from my basis  the monies I received for this judgement, on this stock?
