I'm attempting to file an amendment to my 2020 returns. Where do I find which forms to print and include? This isn't really clarified.

I see forms and print center. There is a choice for "all official forms for filing" but this is for regular e-filing, also it seems too short which is maybe just because I have simple taxes. Also, my state taxes explicitly say "DO NOT MAIL THESE FORMS" so I'm just very confused on what to do. Does anyone know anything about this? Thank you.

Do not include your old 1040 nor your revised 1040 because the Form 1040-X reflects any changes there and becomes your new tax return.

Include any new/corrected document only if it shows federal tax withheld, and include in order only those Sequence Numbered tax forms and Schedules that changed or were added due to your amendment.
Attachment Sequence Number is on all the forms and Schedules that come after 1040.
Mail to the address shown for your location in the Instructions for Form 1040-X.

If you are using TurboTax you have to do this by visual comparison. The program won't break out those pages for you.

refer to your particular state's revenue department for instructions for assembling and mailing a state amended tax return.
