[ningji]

Hi, say A and B has a joint Charles Schwab stock account, each has 50% ownership.

Last year the total gain is $100 for the whole account.

After i imported tax doc from Charles Schwab into turbotax, seems A's 1099-B is still reporting $100 capital gain. So where to how adjust this amount to be $50 in turbotax please ?

are you married to the joint owner?

If so, are you filing MFS ?

A not married to B, they are brothers,

but both have their own families.

so A and B files tax return for their own family.

the one whose SSN is listed should file it, and reach an agreement with the other to recover half of any tax consequences.
