What is acrued market discount and why isnt on my 1099-B?

[joejrx100]

Turbotax says I should enter an amount in Box 1f but it doesnt appear on my 1099-B.  Should I just leave it blank in Turbotax?

If box 5 is checked, box 1f may be blank.  In any event, you should leave the box blank if there is nothing in it.

The accrued market discount is a discount bond's increase in value resulting from the approach of its maturity date rather than a drop in interest rates. This occurs because the holder will receive the par value in full upon maturity, regardless of the amount by which a bond was discounted at the time of purchase.
