No.  If you do that, TT releases all suspended losses to your return.  In this case, since those suspended losses are to remain suspended, and eventually added to ETP, its easier to leave that unchecked.  TT will leave the losses suspended.  Then, in 2018 just add the SXL losses to your ETP entries (there's a spot in the interview where you're asked about carrying over prior year losses -- handle it there) and delete any SXL K-1.
