Question on cross-year wash sale reporting for fidelity

[garfmaj]

I have sold multiple stocks (via RSUs) with a loss in December 2024 which count as wash sales. I purchased no more stock until March 2025.
Normally fidelity will track wash sales and properly update the adjusted cost basis of a future sale to include them (as described here).
However it seems like this didn't happen for my stocks sold in December. They show as wash sales but the adjusted cost basis of the following purchase's sale is not adjusted. Is this normal? And if so will they be counted in any tax forms next year? If not, am I able to just adjust the cost basis myself?

"the following purchase's sale is not adjusted."

what is the Date Acquired and Date Disposed on this transaction?

What is the Date Disposed on the wash sale transaction?

By IRS rules, the adjusment goes on the earliest triggering purchase in the wash-sale window. and proceeding in order untill all the disallowed shares are assigned.

So it is possible that a later sale after wash sale  shows no adjustment, particularly if your sale rule is 

Last In,First Out

"the earliest triggering purchase in the wash-sale window"

That's been my interpretation.

Actually, the IRS Pub does not say that.

it says "the earliest purchase" 

I let the broker do it's job of tracking my basis, as required by IRS.

I tried in the past to understand TD Ameritrade's assignment rule, but I could not figure it out.

The wash losses are not accounted for any in any earlier sales. Here are my only sales in the 30+/- day period.
I'm just not sure how fidelity would ever account for these wash loses in future purchases either as they'd be past the 30-day window (next purchase is in March). Maybe the order of the sales is such that I just cannot account for the wash sales, but that seems weird.

I also have no idea where the 297.94 cost basis adjustment comes from in the last stock. It doesn't match any other numbers. Maybe I just need to chat with Fidelity directly.

		Gain	Cost basis adjusted by (from purchase price)	Disallowed wash sales
12/08/24	12/10/24	-1544.88	0	-1544.88
12/08/24	12/10/24	-662.69	0	-662.69
12/08/24	12/10/24	-394.38	0	-394.38
12/13/24	12/20/24	-13.37	297.94	-311.31

Following up I called Fidelity and had a sale on Jan 2nd I missed when looking at the history. Still not sure where the 300$ is coming from, but I will trust fidelity's logic. thanks for the help!
