amend Net Operation Loss for the current year

I just realized that TurboTax doesn't calculate NOL (net operation loss). Since I already filed, I need to amend my tax filing so the loss could be carried forward to the next year. I opened TurboTax new file, clicked on the "amend" button, imported the current year tax file. I then searched "net operation loss". I jumped to that page. What I found was that TurboTax asked me to enter the last year's NOL. This was not what I wanted. What I wanted was to enter the current year's NOL, not last year's.

How do I amend the file so to enter the current year NOL? Thanks.
