for each 1099-B you enter summary totals for each type A short -term basis reported to IRS
type B short-term basic not reported to IRS
type C neither proceeds nor tax basis reported to IRS
types D, E, and F are similar but long-term
then, what wasn't mentioned is that you have to print out each 1099-B and submit it by mail with IRS form 8453.
follow the instructions because there's a time limit for submitting once the federal is accepted - check the 8949 box
