I have a question about RSU cost basis. I did see one question kinda like mine,and the answer was to delete the row with the issue, and enter it manually, but I want to see if my case is the same. In my case, shares were witheld for tax purposes. Over a year later I am selling the shares (all in that lot). My brokerage reports the cost basis based on how many shares I netted, at the price on the day they were vested. But TurboTax is calculating the cost basis based on the tax I paid.
Example: 20 shared distributed, 8 withheld to cover taxes. Assume $10 per share.
So, my brokerage account would say my cost basis is (20-8)*10= $120, but TurboTax is calculating my basis as 8*10= $80. So, which is correct? I am assuming the brokerage is correct, if that is true, how do I fix it in TurboTax?
Also, what is on my 1099-B is different than the supplemental stock plan detail, and TurboTax is asking about the supplemental details.
