Are their tax schedules that do not go with returns (ie historical schedules)

[gl88201]

is there a schedule showing the tax calculation

[BillM223]

You can see the tax rate schedules and tax tables in the older IRS 1040 instruction books. 

For example, if you enter "IRS 1040 Instructions 2021" The odds are very good that the first hit will be the instruction book for the 1040 for Tax Year 2021. The Tax Table can be found in the Table of Contents.

Does this answer your question?

After you have filed your return and it has been accepted by the IRS, you can elect to print it and/or save it in PDF format. (HIGHLY RECOMMENDED!).  If you elect to print/save *everything* then the printed/saved PDF file will include all forms and calculation worksheets.

Otherwise, the "forms for your records" or "forms required for filing" will not have all the forms & calculation worksheets used by the program.
