TurboTax is only showing $300 where it should be $600 for married filing jointly.
"Usually taxpayers who take the standard deduction cannot deduct their charitable contributions. The law now permits taxpayers to claim a limited deduction on their 2021 federal income tax returns for cash contributions they made to certain qualifying charitable organizations.
These taxpayers, including married individuals filing separate returns, can claim a deduction of up to $300 for cash contributions to qualifying charities during 2021. The maximum deduction is $600 for married individuals filing joint returns."
