Balancing Copper Reaction & Finding Products

The purpose of this chemistry lab was to prepare/synthesize Bis(2,4-pentanedionato) Copper (II), which is also known as Cu(C5H7O2)2

I was given the following format for a chemical equation in a lab that needs to be balanced:

Cu2+ (aq) + 2 base-n (aq) + 2 C5H8O2 (aq) → Cu(C5H7O2)2 (s) + 2 H(base)1-n (aq)

*The 2+ and n's are charges I'm assuming*

My copper source was CuSO4•5H2O
My base was NaHCO2

So I tried plugging in my sources for the equation and this is what I got (but I know it's wrong because the sulfur atoms are missing and I'm not sure how to balance it properly)...

CuSO4•5H2O (s) + 2 NaHCO2 (aq) + 2 C5H8O2 (aq) → Cu(C5H7O2)2 (s) + 2 H(NaHCO2) (aq)

Can someone please tell me how I determine where the sulfur is placed and help me balance this?

Your reaction equation should be net ionic - so you don't have to care about sulfate.
