I noticed a difference on my 1099-B vs Quicken on the sale of some Merck stock. I figured out that there was a spinoff of Organon in 2021 and Schwab reduced the cost basis of Merck and added the shares of Organon in my statements. Schwab only downloaded a "Shares added" transaction for the Organon stock that was spun off. I was able to modify the transaction to add the cost basis and date when I sold the Organon stock in 2022. However, the cost basis for Merck was never adjusted.
I noticed that there is a "Corporate Securities Spinoff" transaction in Quicken. Before deleting the "Shares Added" transaction and entering the "Corporate Spinoff" transaction, I would like to know the ramifications.
Will this cause any problems in my sell of Organic transaction or will it just show a short sale that I can modify later?
How will the cost basis for Merck be shown in Quicken? Will it be a new transaction?
Thanks in advance for any feedback.
