Hello, my spouse has a joint investment account with her sister who lives in another state. My wife is the primary account number had has a majority share (55%). We are filing married jointly using TurboTax.
The brokerage produced three 1099's (DIV, INT and B) which I imported into the software (for the full amounts). For DIV and INT there's an option to make adjustments to the income amounts due to being a nominee.
However, this is not an option for the 1099-B. How should we report her share of the gains and losses? There are over 50 transactions here. Should I manually correct each proceeds amount to show her 55% portion? What about cost basis? Is there another way to do this that doesn't require me to have to hand edit dozens of transactions?
