When Ammonia solution is added to Copper sulphate, at first a precipitate of Copper hydroxide is formed. If excess ammonia is added, finally a deep bluish solution of Tetraamine Copper(II) Sulfate is formed
The products are Sodium Nitrate and Copper Hydroxide.
When an Ammonium solution (NH4OH or simply NH3 with water) is added to Copper Sulfate (CUSO4), it forms what we call a "complex". It is called the Tetraamminecuprate(II) complex. The color of the soultion is deep blue and may form a white precipitate. Here's the reaction: Cu2+ + 4NH3 -----> Cu(NH3)4 (with a 2- charge) Only copper reacts with the ammonium, so there is no need to include the sulfate (SO4) and the hydroxide (OH-)
The reaction forms aluminum sulfate and frees copper.
Copper sulfate is a reactant in the equation as stated, because it is present before the reaction has occurred and no longer present afterward.

Copper sulfate (II) CuSO4 is blue; ammonia is a colorless gas. If you mix ammonia water and copper sulfate solution, you will actually form a Brilliant blue copper-ammonium complex that is very pretty. Copper sulfate is blue by itself and anhydrous ammonia is a clear gas with a choking odor.

It forms a complex - Copper (tetraamine) sulfate which is a deep inky blue color
Try it on your own. (Best answer for your problem is your action)
Copper is a metal element. It is not reacting with ammonia.
In the presence of ammonia and copper, hydrogen peroxide will decompose, liberating oxygen gas. The oxygen gas dissolves in the solution and oxidizes copper to copper (2+). Then the ammonia reacts with the Cu2+ forming a complex with deep blue color.
NH4OH + CuSO4 = CuNH3
