Ok, you got me curious. No default position in all Cessnas I have flown.
Not in the Bo. Nor in the Tobago. Not in the Cirrus nor the DA-40 or the
-20. Nor any other plane I can remember INCLUDING the big airliners in
MSFS.

The position where the control surfaces align with the stabilizer, that is,
no deflection upwards or downwards. At least that's what I interpreted the
expression to mean. I freely admit I'm clueless, though.

NB that I'm not saying that this position is necessarily marked anywhere,
nor that it is relevant to actually flying the plane.
