What 1040 pages do I need to mail to the IRS for 2021. Turbo Tax prints vouchers for the next year. What pages do I really need to send?

[DoninGA]

You have to send the Form 1040 that you have signed and dated.  You also have to send any other forms or schedules which have an Attachment Sequence Number located in the upper right corner of the form or schedule.  All your forms W-2 and 1099 that have taxes withheld need to be included with the mailed tax return

The Form 1040-ES are NOT sent with the tax return.
