TurboTax program is not adding $300 cash contributions to standard deduction

The 2021 summary of deductions page shows my $300 CHARITABLE CASH CONTRIBUTION.

 

The program says the standard deduction is 12,550.  Then, just below that shows the $300 cash donation. Then, reflects a total of 12,550 in deductions.  The very next page shows "the standard deduction of 12,850 is right for you.

 

BUT, then in the wrap up, the program again shows 12,550 in "Federal Deductions we found for you."

 

Calculation error shows up in two returns that I am working on.
