I am using Turbotax deluxe (the download version) to file 2020 tax, but each time whenever I try to amend my return, it display "The Amended Returned Area will be ready soon", but I see in the forum that other people is able to amend the return, do you know I still can't amend the return

Then update your program.  There was an update yesterday March 26.

If you're on a PC, open TurboTax and select Check for Updates from the Online menu near the top. On a Mac, simply quit and reopen TurboTax. If there are any updates, you'll be prompted to download them.

Yes, that fix the problem. But unfortunately it doesn't seem to be a way for me to get back to the data that I have already file with IRS, any suggestions? (I didn't know I am supposed to make a copy before I touch the original return)
