Are they returns with multiple states?  You may not be able to transfer those until the state modules become available.  EDIT:  No I just checked this, it pulls over no matter the state.

You really shouldnt transfer anything but some tester sample files yet  

Each year there are issues with returns that get transferred in before January...certain things dont carry over as they should and you end up having to delete everyone and re-transfer.

(Ive got a few dummy files and my own that I transfer in early, I generally end up deleting my own and re-transferring it back in January.)
