Sent my first CA quarterly tax pmt last Mar 15 using the amount and address provided on my Turbotax form. Payment was returned by the PO today. Address was incorrect.

Have not heard that complaint before, did you use the address TurboTax provided? 

Did you check to see if you copied it correctly?

This is the address on the CA website
