Stock Sales - Must Mail 1099-B

March 4, 2024

Have others encountered this when entering stock sales using TurboTax for 2023 taxes?

If I enter stock sales by Section Totals then go to Forms View, Capital Assets Sales. At the bottom of the screen, it says "You'll need to mail a paper copy (of 1099-B) to the IRS".

This does not occur if I use the One By One option but that runs the risk of entry errors if one has many transactions.

Is this a new requirement or because I sold stock and funds with a basis that was Not reported to the IRS?
