Schedule 5 is a new form this year. It is automatically created for certain situations related to one's tax return if estimated tax payments were made OR if there are refundable credits such as the premium tax credit, excess social security withheld, or credit for federal tax on fuels.
If you need to edit something on your return related to Schedule 5, you
will need to go back to the section that it relates to such as: estimated tax payments or 1095-A (premium tax credit). You can type either of those in the search field and select the Jump To option to be brought to those sections of TurboTax.
Schedule 5 is new because the 1040 form was
revised in 2018. The 1040 form is now a shorter and much of the additional
information that would be reported on it has been moved to six different
schedules (Schedules 1 to 6) Also, note that the 1040A and 1040EZ forms no longer exist.
