Intuit should put a warning with the alert that 1040X isn't ready, stating DO NOT UPDATE YOUR TAX FILE TILL YOU CAN AMEND THE RETURN when 1040X is ready.
In my case I spent hours updating my filing since after I got the alert that 1040X isn't ready, on the bottom right the box said CONTINUE. So I did and it put me into the return so I thought I could update it.
