How do you write the balance equation for removing sulfuric acid with sodium bicarbonate and water remove by magnesium sulfate? Thanks.

What have you tried so far?

And your question is not clear. You want to remove sulfuric acid using sodium bicarbonate and magnesium sulfate?

I think we have two separate reactions. First, the neutralization of sulfuric acid with sodium bicarbonate. The second would concern the use of anhydrous magnesium sulfate as a drying agent.
Reactions of carbonates and bicarbonates with acid have been covered here ad naseum. Magnesium sulfate picks up water and becomes a hydrated crystal, MgSO4.nH2O, It is an excellent drying agent, often used in organic synthesis.
