My 1099-B has a section "Federal / State Taxes Withheld", but I don't see this section option in TurboTax. No other boxes filled for that sections. How do I enter this?

Tax withheld is not included in the other section I have for the "Covered Short-Term Gains or Losses on Gross Proceeds" because there is not one to one relation (one tx withheld is related to more than one sale).

type tax payments in form search box then jump to it.  on one of the lines there is a place to enter federal and state withholding form 1099-B.  you only need to enter totals

Hi @Mike9241, I know where the input box are, the thing is that based on my 1099-B, I should report these entries in a separate section for tax withholds (Federal / State Taxes Withheld), not inline as part of with my sells (Covered Short-Term Gains or Losses on Gross Proceeds). 

Event if I want to report inline, I cannot the one to one mapping from the withholds vs the sells, so my option could be to report these in separate lines under "Covered Short-Term Gains..."), but validation fails because those lines don't have a Cost Basis entry (box 1e):

Check the example below (notice that only 1c, Box 4 and Box 16 have some data):

Thanks!
