I'm having the exact same issue. That is, I got a consolidated 1099 from my broker account. It shows several CD's that matured this year on a 1099-B, with the full sale (maturity) amount in Box 1d. However, there is nothing entered in the cost basis under box 1e. So, it's calculating the full amount of each CD as earnings, rather than just the interest, which is shown separately on a 1099-INT. Presumably, the cost basis is exactly the same as the maturity amount, but how do I report this correctly?
