@alan24bell   Are you in a Federally Declared Disaster Area, and your tax extension is until January 31st?  If not, it is too late to carry it forward, and it MUST be carried back now to your 2014 tax return.

As for how to attach a statement explaining the NOL, I would include Schedule A of Form 1045 and mail it with the rest of your tax return (it is too late to e-file through TurboTax anyways).

No, TurboTax does not do anything automatically with NOLs, so you need to manually insert it.  It will show up as a negative number on Line 21 of your Form 1040.  If you type "NOL" into the search box in the program, it should bring you right to the correct area.
