Deductions & credits

Sorry but your response does not address the problem I'm having. I have been doing my taxes on TurboTax for over 10 years i.e. I know what I'm doing. The issue is that I have "money" contributions of $3972 and my filing status is "Married Filing Jointly", my personal deductions do not exceed the standard deduction so the system should and it did last year assign the proper deduction of $600 (last year it gave me properly the $300). The "Smart Check" does not find a problem, however, when I go through the "Analysis" it comes back with an error "Charitable Contributions has an unacceptable value" and it shows the value of $300 in the entry box. Once I change it to $600 the error clears, however, if I go back to review any of my entries I get the same error with the $300 showing up again. Where it is getting the $300 I can't determine because the "Data Source" is greyed out. This is not a user problem, there is some sort of bug in the program. I need to enter "money" contributions so I can have the carryover.
