Weird K-1 error in QBI passive loss column for an MLP

Hi all,

 

Just putting the finishing touches on my taxes, and I'm getting this strange error.  The error check told me that an entry was needed for the QBI passive loss column.  For some reason, it wasn't filling it in with the values I had entered.  The left column (Regular Tax) was filled in with an operating loss of -1,577 for 2020.  (Most midstream MLPs have operating losses most years due to depreciation, despite positive cash flow.)  But the right column (QBI) was left blank, and this threw an error.  This wasn't a problem in last year's taxes, or 2020's taxes.  But it suddenly shows up now.

 

Yet when I fill in -1,577 manually, which is the correct value, it does the following.  1,577 suddenly appears on the line for 2018.  This is obviously wrong, since I didn't even own this before 2019.

Apparently, the only value it will accept is zero.  But that's wrong.  It should be -1,577, which is the operating loss for 2020, just as -939 was the operating loss for 2021.  What's causing this?
