You are entering it wrong because it is not to be completed in the Forms section of the program.  Go back to step-by-step and enter the stimulus payments you received in the Federal Review section.

Okay! I tried that and the information I have in those boxes is correct.

My only option from going through any section is still "Check this Entry". It won't let me do anything else. I even tried clearing everything and starting over, and I'm having the same issue.
