Downloaded pdf of my tax return is not a complete copy. How can I download an actual copy of my returns?

I actually have a copy of my 2020 return. I compared it to the one downloaded through turbotax and the one downloaded is about 20 percent of the content. It doesn't include any w-2 or other attached forms. How can I download an actual copy of my returns? Do I really need to submit a claim with the IRS? It seems weird that turbotax is not mentioning that it seems to have thrown out a good amount of tax data.

 

*Update: I do want to clarify that I know the original W-2 forms are not included. There should be a tax summary of the w-2 forms though that is just part of the return. I'm literally telling you guys that I downloaded my 2020 return 2 years ago. I downloaded it again today. I compared them. About 80 percent of the original tax document was stripped from the copy that is available today. THAT is what I want to know about. Why on earth did turbotax delete a huge amount of tax information without informing anyone?

 

*Update 2: Here's some pictures! Look at the dates and names of the returns and look at the file sizes! What gives? The new download is 27 % the size of the original tax download. So that means 73 percent of the content is missing in the new document.
