Bunching 2-3 years of charitable contributionsHo

I have given almost 2 times the standard deduction in 2023 for the last 3 years combined.  The high standard deduction means they are worthless (less than) for tax credits year by year.  However, if I bunch them, they are more than the standard deduction.  TurboTax does not see to provide for this ability in the app.  Is that true?  How can I bunch charitable deductions for 2023?  I do not see any info on the Schedule A for either for this "bunching" option.
