Update for anyone else who may find it useful:
You need to fill out Form 8283: https://www.irs.gov/pub/irs-pdf/f8283.pdf
You can calculate the "Fair Market Value" of the stock(s) you donated by averaging the highest and lowest price of that stock on the day you donated it. I used this page to find that, but you can replace "MSFT" in the URL with whatever stock it is you sold.

Thanks! I guess I've been spoiled with a life partner who is a very good baker and being in NYC where there are already some incredible vegan bakeries. But in my experience even many grocery store cookie mixes are vegan if you just substitute aquafaba or something, and I personally cannot tell the difference.
Disclaimer: I am mostly skimming as there's a lot to read and haven't gotten through it all. But I do believe part of the idea with FarmKind is that the donors are already sympathetic to animal charities, and agree with the premise of effective animal charities, but also just want to get some warm fuzzies in as well. As opposed to most of their money going to something they do not agree with or have any care for.
