Deductions & credits

Thank you for replying, but as I think I stated in my original question: I only own and use 1 single vehicle.  That's what makes the duplicate "undefined" listing such a puzzler.  The system seems to think I still have a second vehicle; I did own an earlier MKZ Hybrid, but that one was totaled and taken out of service during 2019.  It no longer appears in my QBSE.
