After you file

Just follow the interview ... everyone will see this screen in the Federal Review tab ...

The question about the amount you got in the advance stimulus payment doesn’t happen until the END of the interview.  By then the program has already calculated the credit and has included the amount in the refund meter you see at the top of the screen.   UNTIL you get to that screen where you can indicate how much you actually got in the ADVANCE payment the program cannot know what the correct amount really is.  So once you enter in that amount the program adjusts the credit accordingly depending on how much you already got and the refund meter will change appropriately.  

I think the timing of this question is not ideal however the Refund-O-Meter is not to be believed until you have completed the entire interview process.  This is a question we will have to answer a lot I fear just like the "missing" EIC & CTC credit questions.
