Hi,
Forms are generally more formal and similar to the official government forms whereas Easy Step uses less "taxy" terms and provides more guidance for users. The language and experience of the ONCARE tax credit in Easy Step & Form are different but achieve the same goal.
Since the children were supported by both you and your spouse, both of your incomes were used in calculating the tax credit whether Easy Step or Forms mode was used; see line 5 of ON479-A (ONCARE).
