The instructor mentions that temperature at standard operating conditions is 20 Deg C and at this point fuel compensation should be 0. However, in the attached 3D temperature compensation table zero compensation is at 0 Deg C. Do the values in the table need to shift two columns to the right as the axis is labeled Inlet Air Temperature Deg C vice delta T?

For what’s it worth, I’d would say you are correct. The lecture was presented in NIST Normal Temp & Pressure Units. Although mis-spoken as Standard Units. While the attached chart is in International Units. Shifting the chart values 2 right would place it in NIST values.

Maybe the HP Academy moderator would like to verify this?
