I am working on my stock section and am being asked to attach the 1099-B. I used TradeLog to compile my 8949. Should I attatch the 8949 or the 1099-B?

If TradeLog gave you a completed Form 8949, why wouldn't you use it?  That's what you're paying for.

How are you entering your stock section?

Some users are asking on the forum about this offer from TurboTax to load your 1099-B.

I'd like to understand what triggers it.

In the previous years, you could not do that.
