If you read the definition of enthalpy of formation, you will realise that aqueous solutions can't have one.
Solid KCl will have an enthalpy of formation (which you can look up) and gaseous K+ ions and Cl- ions will have enthalpies of hydration, and solid KCl has an enthalpy of solution. The last one is probably what you're after.
