Investors & landlords

I have a similar question as well.  I have RSU's that vested in 2021.  I did not sell any but the company did sell off shares to satisfy the taxes (Federal, State, FICA, Medicare, etc.).  All income and taxes are reflected in my W2.  There is no 1099-B for the RSU tax sale.  What gets entered into Turbo Tax other than the info on the W2? 

1. Do I need to show the sale of the shares withheld for taxes in the Turbotax Investment Income section or is this not required since it is already in the W2?

2. If it must be shown in the above section, Is the cost basis only for the shares sold to satisfy the taxes (in other words proceeds equal costs to cover taxes)?
