SDI tax is deductible and is included in state and local tax, In TurboTax put the CA SDI in box 14 instead of box 19.
Although TurboTax has never supported Form 1040NR: U.S. Nonresident Alien Income Tax Return,
we have a partnership with Sprintax offering a nonresident tax filing solution
to our TurboTax customers.
