@roalddahl14 , there is no short-term capital gain -- you just pay ordinary income rate. Only assets held over one year get Capital tax rate ( for most people it is zero or 15% , based on your other income ).
One way to see the impact ( very roughly ) and assuming that you are doing your return on widows downloaded / CD version, is to (a) open your filed return and then save it under a different name. This will result in your original return saved with original name and a new one with a new name and usually open. (b) now go through the return and add a dummy 1099-B ---- using your warrant price as "Basis" and the selling / FMV as your sales price --- this will show you what happens if you hold only for short-term and changing dates to make it long-term. These what-ifs will give a better directional figures while preserving your confidentiality. Note here that for trying out long-term / capital gain scenario, you have to show a buying date of at least one year before the selling date ( Turbo will not allow future dates i.e. past the current date because you are using the 2023 software ).
Hope this helps.
