Amended Returns needs mailed

I amended a 2020 Federal Tax Return because I discovered some college related items were missed. TurboTax didn't allow me to eFile. Instead a PDF was created and I need to mail in my 2020 Amended Taxes.

 

Inside the PDF there are these forms: 1040X, 1040, Schedule1, Schedule2, Schedule3, Form 5329, From 8863, Form 8889.

Do I need to submit all of these forms or just the 1040X?

 

Thank you
