ProConnect Tax has even less areas to enter this than Lacerte does. The "help" articles are not much help https://proconnect.intuit.com/community/schedule-k-1/help/basis-limitation-frequently-asked-question... and https://proconnect.intuit.com/community/schedule-k-1/help/basis-limitations-for-k-1-losses/00/5162 do nothing to aid in the how to. 

Bottom line, keep some notes and maybe a spread sheet on the side and "make it work".
