I am having the same issue.  For Entities that have been around prior to this year, the Federal percentage is out six digits, which is what AZ used to use.  Now AZ uses four digits.  I assumed based upon rounding that was what was causing the diagnostics.  I have a new entity this year and I purposely only used four digits for the Federal percentage so I would not get the AZ diagnostic.  I still have the diagnostic on a new entity where it does total 1.00.

It says it is a critical diagnostic, but doesn't say e-file diagnostic so I'm hoping I can e-file without issue.  Fingers crossed.

Anyone else E-File an AZ partnership return yet?
