K-1 MLP Sale Mess- Help!

I know there are a lot of questions around K-1's for MLPs.  So here's another one.  

 

I sold an MLP in 2021.  It's reported on my 1099-B.  I know that the cost basis is wrong and I need to adjust it per the K-1 package.  Fine.  

 

1.  TT autogenerated another 8949 for the sale marking it as a transaction NOT reported on a 1099-B.  It obviously is reported there.   How do I get rid of this 8949? Deleting it does not work?  I can't change the designation of F(not reported on1099B) to E(reported on 1099B w/o cost basis).  

 

2.  The TT Partner's Share of Income Credits etc (K-1) Section C shows this as a non-passive loss for Schedule E.  But as an investment for me it is a passive loss.   Is Section C right (e.g. it's non-passive)?  

 

3.  The K-1 package tells me to enter a number in Form 4797 Part II line 10 but no entry to that line/form is allowed by TT.  Where does that value  get pulled from in TT?

 

4.  I am also instructed to enter a value on Form 6251 line 2k but likewise I can't enter any info there.  Where does that come from?

 

5.  The MLP K-1 has the box checked in Part III line 16 (schedule K-3 attached if checked).  TT is marking that an an error, because I have no K-3??  There is no K-3 on TT Premier.  I find the K-3 on the IRS site but I have no idea what to do with that and the K-1 package is silent on this (other than the box being checked).  Should I leave it checked or uncheck it?
