There is a new line on the 2023 Partnership K-1s in the liabilities section - "Check if any of the above liability is subject to guarantees or other payment obligations by the partner.  See instructions".  

The instructions lead me to believe that I should put code "x" in box 20 and then attach a statement with some detail - how do I do this in Lacerte?  I have figured out how the check the box for line K3, but can't figure out how to get code X in box 20, nor how to attach the statement. 

Thanks!
