I was assuming that the CARES changes had been incorporated for this form/worksheet because TurboTax seems to apply the correct deductions for cash contributions up to 100% of AGI, a provision which didn't exist prior to CARES.
Also, the bug I'm reporting is about the treatment of cash contributions to private foundations, which is unaffected by CARES - I only mention CARES because TurboTax now puts such contributions under the CARES 100% column when it should have remained in the old 30% column.
