If your 2018 federal tax return, Form 1040, included any other forms or schedules that supported your tax return, they need those other forms or schedules.
A schedule is just another page that may be included with your tax return depending on the type of income being reported or deductions being reported.. Such as Schedules A, B, C, D, E, F, etc.
Additional forms or schedules will have an Attachment Sequence Number located in the upper right corner of the form or schedule.
If your tax return was fairly simple you may not have an other forms or schedules other than your Form 1040.
