Does Fidelity Autolatically Adjust for Total Wash Sales in their form 1099-B or Not?

Hello,

In the consolidated 1099 tax form from Fidelity, section 1099 – B, there is a note that says “Total wash sales (disallowed loss) are included in the total cost basis and, therefore, calculated in the realized gain/loss.”

However, in a recent post, Fidelity commented that they don’t adjust their realized gains/losses for total wash sales in the 1099-B form.

So which one is it, do we need to adjust the realized gains/losses number for the total wash sale or not?

in my form, it seems very unlikely that they automatically adjusted for the total wash sales in realized gains/losses number, but I’m confused by the above note they have in the form regarding automatically adjusting for total wash sales.
