Still have "Form 3468 errors". Can someone help?

On my K-1 there is no AJ for Box 20 that seems to give an error to many. I have only N,V,Z for Box 20. But I still continue to get the Form 3468 error (13 times in the Review).
(Someone asked & I have nothing in Box 15.)

I've tried deleting the form & saving TT, but that dreaded form (for which I have NO answers) keeps coming back.  Hours spent trying the various things suggested for this K-1 ! The suggestions don't work for me.

How can I correct the errors & file taxes with TT showing 13 errors due to form 3468????
