Notwithstanding section
72, in determining the extent to which a distribution is a qualified charitable distribution, the entire amount of the distribution shall be treated as includible in gross income without regard to subparagraph (A) to the extent that such amount does not exceed the aggregate amount which would have been so includible if all amounts distributed from all individual retirement plans were treated as 1 contract under paragraph (2)(A) for purposes of determining the inclusion of such distribution under section
72. Proper adjustments shall be made in applying section
72 to other distributions in such taxable year and subsequent taxable years.
