Why is turbotax recommending the standard deduction for me?

Turbotax is saying that the best option is for me to take the Standard Deduction this year...

When I go back and look at my deduction categories for 2020, here is what I find:

Gifts to Donations and Charity:                             $2,992

Unreimbursed Employee Expenses:                    $1,141

Mortgage Interest:                                                   $14,084

Real Estate Taxes:                                                    $5,575

State and Local Income:                                        $6,113

Vehicle Registration Fees:                                     $107

State and Local Taxes Greater than $10,000:    ($1,795)

TOTAL                                                                       $28,217

When I go to the next page where it gives me the option to change my deduction to the Itemized approach, it is saying that my total is only $21,271:

Can anyone tell me why Turbotax is only finding $21,271 in itemized deductions instead of the $28,217 I'm adding up myself?

Thanks!
