Pub. 17 closely follows Form 1040, U.S. Individual Income Tax Return, and Form 1040-SR, U.S. Tax Return for Seniors, and their three Schedules 1 through 3. Pub. 17 is divided into four parts. Each part is further divided into chapters, most of which generally discuss one line of the form or one line of one of the three schedules. The introduction at the beginning of each part lists the schedule(s) discussed in that part. The table of contents inside the front cover, the introduction to each part, and the index in the back of the publication are useful tools to help you find the information you need.
