I have the same issue in my 2021 Sales Tax Deduction calculation. I live in unincorporated DeKalb, GA and that option is not listed but Tucker,DeKalb,GA has the same sales tax rate. TurboTax gives me a deduction of $1,700+ while the IRS web site calculator gives me a deduction of $1,900+.
I'm retired and GA excludes some retirement income from taxes so even the TurboTax state and local sales tax deduction is greater than the state income tax deduction.
Thanks.
