Deductions & credits

"For tax years 2020 and 2021, the contribution limit is 100% of your adjusted gross income (AGI) of qualified cash donations to charities." My turbotax took advantage of this apparent change but the IRS rejected it. I am told by others that this change only applies to "50% charities." Mine were all "100% charities". My concern now is that my file copies of Turbotax 2020 will not properly calculate my carry over for my 2021 taxes.
