Investors & landlords

Hello,

 

In July 2019 I transferred company stock from my 401k to a brokerage account via the NUA method.  I recvd the 1099R statement with the cost basis of the account at that time so that part of it is fine.  However, I have since sold some of the shares in the brokerage account but there was no cost basis showing for these shares.  How do i figure out the cost basis of these sold shares Since I was buying stock for 29 years when this was in my 401k or Is the cost basis the closing price of the stock at the time it was transferred to this brokerage account? 

Thank you in advance.
