I received a Form 1099-b. The security is noncovered. There is no value in 1e so what do I enter for it?

1e is the cost basis of the stock.

You need to try to determine the best you can when you bought it, for how much, and how many shares.

Do some research of past broker statements, the internet, whatever you can, especially if the amount if material.

Otherwise, the IRS will require you to enter $0 for cost basis. 

So for example, if I knew I had QCOM and bought it is 1999, and I knew I bought 100 shares, I would use the average cost per share at that time.  I would then document my tax folder as what I used, what diligence I did in finding the cost basis.  

As long as reasonable, logicval method was used, IRS seems to be OK with it.

Now if the sale is very small, I might just enter $0 and be done with it.
