have carry over losses forgot to file form 6198

[Reid Isaki]

I looked at filing an amended return but it doesn't really have any line items for carry over losses from rental property from the previous year. I know I needed to file a 8582 and a 6198 but only filed the 8582.  Is it possible to amend this or am I just out of luck on last years losses? I had excess of 5700 in losses last year and want to carry it forward.
