After you file

I'm trying to amend my 2017 return for a second time. In the first amended return, I got a refund of $360. I deleted the 1040X form from the first amended return, and the refund monitor increased by $360. I saved the file and closed TurboTax. Then I reopened TurboTax, clicked the amend return button and selected the file I just saved. I made the new changes, but the 1040X was blank. I would have to fill it in manually. TurboTax seems to understand it's an amended return, but it's not giving me a new 1040X. Any suggestions?
