If I sold shares at a loss in 2023, but received a class action award in 2024, do I need to amend the 2023 submission?

No, you do not amend your 2023 tax return. You will report the class action award as income on your 2024 tax return.

 

You enter the income as a capital gain.

In TurboTax (TT), enter at:
- Federal Taxes tab (Personal in  Home & Business)

 - Wages & Income

Scroll down to:

-Investment Income

   -Stocks, mutual funds, Bonds, Other 

Answer no, when asked if you got a 1099-B. then follow the interview.  Show $0 as your cost basis.  Use the date you received the money as the sale date, not the 2023 original sale date.   If that changes your holding period from short to long term, use "various" as your acquisition date.
