While the Turbtax states "Principal Residence Address Only complete this section if you are 18 or older and you have filed a California resident income tax return in the prior year. • If your principal/physical residence address at the time of filing is the same as the address you provided at the top of this form, check the box provided on this line. • If your principal/physical residence address at the time of filing is different from the address at the top of this form, provide the address of your principal/physical residence in the spaces provided. • If you reside in a foreign country at the time of filing, enter the city, province or state, and country in the city field. Follow the country's practice for entering the postal code. Do not abbreviate the country name. If you are under 18 years old or have not filed a California resident income tax return in the prior year, then leave the county and principal/physical address fields blank." It won't let me type a foreign address.
