That diagnostic appears to be in error.  I was able to replicate both errors in my software exactly as you are seeing them.  See attached. 

In your scenario, the taxpayers should each be distributed their share of the $582 PTE tax paid as a credit on the MD K-1 on Part D, Line 2.   This $582 should also be summarized on Sch B by owner.  If you have $582 on page 1 of the Form 511 line 12, Schedule B and on the MD K-1's you should be able to ignore the diagnostic.  

The same idea applies to the $7,269.  If the amount from page 1 of the 511 matches the Sch B totals then the return is working as expected.  You can ignore the diagnostic.  

We will update the software to correct these informational diagnostics.  They are not helpful to the user in their current state.
