Ask the shop that painted the vehicle. It's usually 7 days for washing and 6 months for wax. How ever each paint system is different and has many variables. If you wax too early you may void the paint warranty.
If it was heat cured, the whole paint booth warms up it could be a couple days, even so most say wait 3 - 4 weeks. Gimpy1 is one the right track. Ask the shop where you got the work done.
