Retirement tax questions

Thanks.  Refundable tax credits was it.  Never qualified for those, and didn't notice the "you may be eligible for a credit" comments when answering the credit questions.  As for how to see how the state refund was calculated, I can't seem to do the print previewing you describe until I pay and file.  It was going back through the credits and deductions questions that confirmed refundable tax credits.  Thanks again.
