Get your taxes done using TurboTax

@dmertz I just got off the phone with turbo tax support and he said that I won't get the credit because I am getting a refund.  He confirmed that making the excess estimated pre-payments  cheated me out of the savers credit.  

So before I believe you had done a fake tax form entry as a test proving that the tax credit worked as expected for a roth conversion.  Could you enhance this test to make some estimated tax payments that signficantly exceed the tax liability to see if the saver's credit is denied?
