After you import the first one, save turbotax and exit, then start up again, and it should work. At least it did for me.
<I did not need to shut down my browser; I shut down TurboTax and restarted it and then I could put my wife's info in for Fidelity.
TT also will not import my 1099-B Futures statement for for the 1256 Futures and Straddles contracts info for TD Ameritrade and E*Trade, so filled it in manually. >
I hope that helps.
