Also had trouble with Federal 1040, line 12b and the charitable contribution if you take the standard deduction and file married filing jointly, and have given more than $600 you should be able to record $600 on line 12b and then on line 12c add 12a standard deduction amount and 12b the charitable contribution amount. At the final review, the number populates back to $300. It then continues to show up as an error. So, I had to manually change the number and fix the errors but not run the error check again.
