Why is turbo tax not adding the dependent tax deduction and job expense deduction to the total itemized deduction amount?

Under the Tax Cuts and Jobs Act (TCJA)  2017, the unreimbursed employee expenses deduction has been suspended in tax years 2018 through 2025. There are some exceptions where you can still use Form 2106 through tax year 2025, including if you were an Armed Forces reservist, qualified performing artist, fee-basis state or local government official, or an employee with impairment-related work expenses.

State taxes: Job-related expenses might be deductible in your state even if they’re not deductible on your federal return.

Where do I enter job-related employee expenses?

 If you are claiming a dependent, you may qualify for Child tax credit or credit for other dependent. 

You might also receive the child and dependent care credit if you paid any care expenses. However, those are not part of the Itemized deductions.
