I didn't see the exact screen you saw that had the receipt info but I tried to amend my return and got some different behavior this time. It prompted me that the payment date was wrong with a wizard that had a textbox and the preview of the section of the 1040 at the bottom. I noticed when I filled out the first textbox with today's date it did not change the date in the 1040 section. I then was able to type into the box there as well and the return seems to have been accepted by the IRS now. Thanks.
