Investors & landlords

Thank you so much @DavidS127.  The explanation and screen shots were extremely helpful to get me going in the right direction related how to enter information for code Z in Box 20.  I did get a screen with boxes.  However, I still have some confusion.  Attached is an image of a portion of the statement with my K-1.  The blurred out portions are just the name of the "business" to protect privacy in a way and because I don't think it's pertinent to my questions.  However, showing the image here will hopefully help make my questions clearer.

question 1) noted in blue box - the description says it's for code AH but indicates information relates to codes Z, AA and AB.   Box 20 of the K-1 itself has codes Z and AH noted to see statement; there is no code AA or AB in box 20 on my K-1.  Could this be more of a "general" thing like in case I also had AA or AB?  Or do I need to be looking for somewhere in TurboTax to enter information related to AA and AB? 

question 2) noted in purple box - what are these numbers?  TurboTax seemed to pull part of them in for code AH but not all of them.  Do I add labels/descriptions in TT for the ones it didn't add.   When I got to the boxes for code Z it pulled in 75 (from the 1 and 74 labeled UBIA).  But the section 199A worksheeet I was entering numbers for code Z had an entirely different (higher) number for qualified property.  Are the numbers labeled as 199A connected to code Z instead or as well? 

Please let me know if you need further info or clarification on my question.

I'll be happy to scan and upload an image of additional info I have if it's needed.

Thank you so much for any help.
