What are the entries for prior year carryovers? Are they in the 50% limitation?  I think I see what you are encountering. 

I suggest you use Ctrl + L to send the return to Lacerte for them to review and get back to you with whether they feel the worksheets are correct or not. I have not run into this and digging through all the worksheets and pub 526 is not something I feel I want to do on my day off. Maybe @IntuitBettyJo could get someone at Lacerte to join in.
