I am not in a Windows environment (and TT Business is only available for Windows), so I can't access the software, but I would recommend reviewing the input section for the K-1's.
In particular, the section for Box L "other increase/decrease" line.
On your K-1 you would have a decrease, and then an increase on your child's.
I would imagine there would be a space for an explanation, and I would just reflect "gifting of partnership interest"
Another option, would be that this gets adjusted in the partner's information section.
I will also see if another "Champ" is able to provide assistance by having access to the TT Business; @M-MTax
