If the Standard Deduction was entered on your tax return then there is no need to amend the 2022 tax return since charitable contributions are an itemized deduction. The total of all itemized deductions must be greater than the standard deduction to have any tax benefit.
Look at your 2022 Form 1040 Line 12 to see if the Standard Deduction was used -
