Where do I enter the amount of Stimulus payment received in 2020?

I just transmitted Federal.  The program did not ask if I received a Stimulus payment.  After transmitting, I read on this site that during the Federal review the question regarding Stimulus payment would be asked.  That did not happen.  I was paid 1200 for myself and 500 for my son in 2020 for a total of 1700.  

 

Where was I supposed to enter this amount?  What line on the 1040?

 

Do I have to amend Federal?

 

Do I have to enter the amount on Illinois State 1040?  Where?  Thanks
