Guyhavingtaxfun,
The federal tax liability worksheet makes you SUBTRACT credits from you tax liability, not add them. In your example you are ADDING the credits. If your federal tax liability is $6950, and you received stimulus in the amount of $3600, then your OR40 line 10 would be $3350. Maybe you didn't answer the questions on the Federal side regarding RECEIVING the stimulus. If you answered NO you didn't receive a stimulus, then the $3600 would not have been SUBSTRACTED from your tax liability subtraction on OR40 line 10.
