Schedule 3 is a new form in 2018. This year the 1040 form was completely revised. The 1040A and 1040EZ forms were eliminated. The 1040 form is now a shorter form and much of the additional
information that would be reported on it has been moved to six different
schedules (Schedules 1 to 6).

These credits are the child and dependent care expense credit, foreign tax credit, education credits, residential energy credit, retirement savings contribution credit and other general business credits. in order to have these credits reflected on your tax return, they must be reported on Schedule 3.
