Standard deduction for federal and itemized for California but no longer have receipt for vehicle purchase. I need to add the purchase date and purchase price of vehicle. I plan to take standard deduction for federal and itemize for state but I no longer have reciept for the vehicle since it is over 10 years. Can I still take deduction? I have the 1098-C and plan to use the value for that but I don't have the vehicle reciept anymore even though I need the exact value from that
