According to IRS, donations of up to $300 by 12/31/2020 are now deductible without itemizing for 2021 filing. However, adding $300 doesn't increase my refund on TurboTax.

I gave over 300 and would like to take advantage of this credit given this year, but it seems the program is not adding that number to my refund.

Does the 300 show up on 1040 line 10b?  Maybe you are already getting back all the refund you can and more deductions won't increase it.

Before filing,  You can preview the 1040 or print the whole return
