Step-by-step explanation:
California itemized deduction:
The correct answer to the calculation of Naomi's California itemized deduction amount is $11,965 Church contributions are a qualified deduction, so we count the full $7,500. The unreimbursed employee business expenses and tax preparation fees would be deductible for federal purposes but are not deductible on California state returns as of the tax laws in place prior to the knowledge cutoff in 2023.
The safe deposit box fee is not a deductible expense for either federal or California state tax purposes. Therefore, the only deductible amount for Naomi's California state taxes is her church contributions, which totals $7,500. However, under California tax law, she might also be allowed a state-specific standard deduction. In conclusion, the itemized deduction on Naomi's California tax return would be her church contributions of $7,500 since other expenses listed are not deductible in California.
