Rollovers and Roth conversions do not reduce the credit. Make sure that you have properly reported the traditional IRA distribution as having been converted to Roth.
The credit is a nonrefundable credit, so if you have no tax liability before considering this credit, you do not receive any credit.
Retirement distributions in the preceding two years and through the filing date of your tax return by either you or your spouse that were not rolled over reduce the amount of new contributions considered for the credit.
