In the top part of the "Maximizing Your Charitable Donations" page, you can see what amount of donations TurboTax recommends you claim for the year. If you want to change that, you can answer "Yes" to "Do you want to override the optimization?" and set a different amount. If you have a spouse/partner, you can also change the amount that you are transferring to their return.

Thank you

Not sure why this happened when I hit 'yes' or 'no', the donation amount I'm claiming from this year ends up in the column  'Donations to carry forward to future years' and the amount is $0 for the amount I want to claim this year.
