Get your taxes done using TurboTax

@brettbrinkman  A couple questions / comments:

• Do you have your own copy of the MMP K-1 for 2021?  I ask, because you mention section L as being blank.  It won't be blank on the K-1 itself, and you're going to want that for future years just as reference.
• Are you following the TT interview, or trying to do this in Forms mode?  I ask because you're referring to entering values directly into the QBI worksheets, and there's no need for this is you follow the interview.
• TT won't track your basis.  You'll need to do this yourself, using the K-1s.  There won't be any tax issues associated with this, unless it goes below 0.  At that point, 6198 comes into play and things get more complicated.  Unless you want to develop real expertise in partnership taxes, best bet is to not let the basis get below 0.
• If you simply follow the interview, the correct info will flow to the forms for filing.  You'll also see a K-1 worksheet in your file that tracks the -865 carryover, and it'll show up in your 2022 return when you use TT to import 2021.
• As long as you used your own money to buy the MLP (i.e., you didn't take out a loan to do it), AND your basis is above 0, then you'd keep checking the "Investment at Risk" box in the interview.  That avoids TT creating form 6198.  Once either of those is not true, you'd stop checking that box and 6198 is brought into the discussion.

Hope that helps!
