After you file

Thanks for the reply. If Turbotax doesn't support Form 1045, how exactly do I file NOL? I know I can download the form, fill it out, then what? How do I let IRS know I'm amending my tax file?

 

Oh! Forget about what I wrote above. I just figured out Form 1045 is for tentative refund. I have no refund because my tax liability is 0. I need to carry forward my NOL for future use.
