My 1099-B has a total of almost $100k of gains but does not show any taxes in block 4. I have transaction confirmations showing that taxes (both Fed and State) were taken out but those don't show on the 1099-B. The notes say that the taxes are not on the 1099-B because they are shown on my W2. How do I confirm that? I the taxes are not on the W2 how do I capture them in my tax return?
