Before April 15 2023, I filled a tax extension 
First,  is tax form 1040 the right form to file tax after April 15?
Second, should I include a copy of tax extension form?

Filing Your Tax Return
You can file your tax return any time before the extension expires.
Don’t attach a copy of Form 4868 to your return.

You would file the income tax return you would have filed (e.g., 1040) had you not filed for the extension.
