The lift that fluent calculates, is just a coefficient between the lift force (lets say in newton) and the 0.5*rho*A*v^2 wich are the reference values that you put in Fluent. Usually the area "A " is the proyection area of the body in the plane perpendicular to the far flow. In this case, i think that you dont need the reference lenght.
On the other hand, if you just want to know the lift force in newton, i recomend you to calculate in report> forces.
