Clarifying footing shear and moment load inputs

My specific situation I’m trying to model is simple: A concrete shear wall sitting on an isolated concrete footing. I have the reactions from my shear wall (vertical, shear and moment). The shear load is acting parallel to the x-axis in my model. This creates a moment about the y-axis.

The way the description is written in Clearcalcs is confusing me. Whenever I talk about moments, I have always referenced the axis that the moment is acting about (“around”). The description and sketch under the load entries labels the “Moment by A”. My question is, do I need to enter my moment about the y-axis in the “Mxx” or “Myy” table?

I’m assuming the shear load parallel to the x-axis should be entered as “Vxx”. but the “moment by A” sketch leads me to think that “Mxx” = moment ABOUT the y-axis (which I have always seen labeled as “Myy”).
