Ok, go to quartus tools menu then megawizard plug-in manager and choose

parallel_add from the arithmetic group. Then set your parameters e.g. bit width, number of inputs, size of output, pipeline stages. Thats all.

then you get the adder component , just connect it in your project.

If the number of inputs allowed in your case is < 40 then you can use two instants...
