I have the same question. If my income wasn't significantly different, I wouldn't need a calculator.
The calculator has been updated and is available for use to estimate your tax refund.

I'm not showing the same max refund on my actual refund as shown on the Retirement Savings IRA calculator tool.
Is there a problem in the software?
located in the review tab of the program. the calculator tool gives a value. When I enter the value for a traditional IRA contribution in the proper section it gives the same answer (which is the same value from the review section), then I click the continue the value lowers. that is the reason I think there is a software issue.
