K-1 from a Form 1065 reflects a loss in box 1, but Partner doesn't have basis to take a loss

[natcpa1]

Can someone please help me... I am doing a personal return for an Active K-1 Partner. Box 1 of his K-1 reflects a loss of (12K). However his basis is (11K). He doesn't have enough basis to take a loss. 

1) How do I let ProSeries basic version know that the partner doesn't have basis to take this loss? Once I input (12K) box 1 loss into the program it automatically assumes he can take this loss- - which he CAN'T

2)Where do I input  basis information and let ProSeries Basic know that this loss needs to get carried forward to future years? 

Thank you all so much for your guidance.
