It's March 2022 and this question is still not answered! And the form doesn't even make any sense. For a donation of appreciated publicly traded securities (not necessarily "stock," as TurboTax calls it), the donation limit is supposed to be 30%, but that's not even a choice. I found that TurboTax was limiting my donations of appreciated stock to 20% of AGI, costing me thousands of dollars! And what the hell do the three choices even mean. since you didn't answer the question. Furthermore, shouldn't these questions apply to each DONATION and not each CHARITY, since if I give $1000 cash to my church it's at least 50% limit, but if I give $1,000 of appreciated stock to the same church, it has a 30% limit.
