@itonewbiethanks 

Sorry I am confused.

For me it was complicated based on answers of @IRonMaN and @sjrcpa however I usually wait to be convinced.

Now you are trying to help me and my confusion is because of last answers I got from other volunteers..

I can not understand this part:    If we refer to Section 1.6, we will see that 1040X is no longer exempt unless it is a dual status return, the original was not e-filed (which makes the amended return ineligible for e-filing), or that it was for tax years prior to 2019, the first tax year e-filing was made possible (which should really be 2021 now based on the 1 + 2 formula).

Of course, there's also the reason that Intuit doesn't allow e-filing of 1040X if the original was not e-filed with their software...  Not sure if that has changed though. You mean, if the original already did not e-filed we can not make e-file 1040-X?

Yes, the IRS needs all these to process the amended return because they need to be able to see what has changed and how the numbers flow.  The 1040X is simply a summary of the various changes.  The IRS is just the same as you - there is no way you could have reviewed and approved the 1040X without those details.

What I understood: I have to attach 8948 and since most of original forms got changed (which I dont know already e-filed or mailed) because of 1040-X,  I should attach all of  new 1040 pages.

 If it is, now I have to back my first question that still unanswered, 

Couple should sign and date handy on page 2 of 1040-X, how about tax preparer? Should I sign and date handy writing or typed-font signature and date are fine?

My client is another state.

Also I did not file original 1040 for him, he is new.

How about page 2 of new 1040 which I made it?

Couple should sign and date handy on page 2 of 1040 or they do not need to do,

Should tax preparer sign and date handy writing or typed-font signature and date are fine?

Thanks for your patience!
