amending federal return doesn't reset to values to 0 for federal but does for state

I see that the latest download seems to allow for the amending of a 2022 federal return. 

 

I am trying to add a 1099-R for a direct rollover, and in fact it shouldn't affect any of the key tax numbers. But when I start the Amending process, the values reflected on my amended form are incorrect, and they show that I should receive a refund. 

 

At the screen "We'll help you amend a return," the numbers reflect my initial filing, which were refunds for federal and state amounts. But after I answer that I have filed my return, and that it's 2022 that I want to amend, TurboTax shows a federal refund of $4,447 and a state refund of $0. 

 

So, even before I start the process, my 1040X is out of whack. I have been poking around with resetting the values to exactly match my previous values, but that seems fraught to me. It seems like a bug in the program, or a problem in my already filed return, which seems less likely, unless it's a hidden problem.
