I was a systems architect, detailed designer, and programmer for over 3 decades. I am certain that adding this text would be trivial and avoid people having this problem. A leading goal of any software is to make the customer experience as friendly as possible. Perhaps you didn't have the problem and cannot relate to the frustration.
Another related example is that TT asked for the taxpayer and spouse's AGI separately, knowing that last year was a joint return. This makes no sense (since there is only one AGI on a joint return) and just causes confusion. This too should be fixed. I call this lazy programming and I would have required my team to fix it immediately.
