Deductions & credits

It didn't work.  I deleted the $406 I donated and imported from It's Deductible.  I did exactly what you said.  The $300 still showed as an error and didn't go away.  I tried changing it, deleting the form, etc, and it ended up causing problems with my taxes.  It won't accept $300 which is what Turbo Tax puts in, not me, and it won't accept $600, because we are married filing jointly as would be expected...we only donated $406.  It rejects any change and actually starts to cause other problems shifting me into tax underpayment penalties.  Turbo Tax took all my entries and said I am best going the standard deduction route, but this charitable contribution issue is wreaking havoc.  Why doesn't Turbo Tax fix this glitch.  I doubt I am the only one having this problem.  Thank you.
