How do I fix my 2021 tax return? I can amend it, then it gives me 158 pages to print off and tells me not to forget to mail it. Do i need to print off all 158 pages?

You only need to print the Form 1040-X and any other forms or schedules that were changed by the amendment, but the original and amended Form 1040 is Not included.  All the other worksheets, unchanged forms and schedules or information only pages are Not sent with the amended return.

Make sure that you sign and date the Form 1040-X before mailing.

Since you must be using the downloaded program simply click on the PRINT CENTER and print the forms in the first option ... forms to be filed will be in there  ...
