Belkys1234, I completely deleted the K-1 and started over, and I ran into the same problem. I tried to find a customer support phone line and couldn't. I was in the same boat and becoming very frustrated until @xtinaissharp posted the tip about checking the box for investment being at risk. That fixed it for me. I've never had a loss either, but noting that the investment is at-risk eliminated the hurdle in the review stage that was preventing me from e-filing. Hope it works for you!
