I have an issue with math on the 540.  Client has a $31 CA earned income credit.  Wants to pay the CA sales tax of $2.  Overpayment now shows $29 - good.  Go down to refund amount and it is $27.  Taking the $2 out twice.  Spoke with tech last week and still no fix.  No easy way to contact intuit.  Called today wait would be over 1 hour.  Poor customer service and tech apparently isn't that good or quick to fix either.
