Kid's tax form rejected for 2023; think we forgot to file 2022 return. what next!?

Sent in a very simple form for our kid to get a few bucks back from 2023 working.

it was rejected. . . wrong AGI. We looked on the pdf; it is the right amount.

 

However, we can not find an email saying it was accepted, or we can not find the exact amount of federal return sent back to his checking or savings account.

 

Our kid got back a very small amount from the state last year; we can find that!

 

I think we completely forgot to file 2022 taxes for him! What is the next step?? can we file both 2022 and 2023 together? need to file 2022 first?

 

please share what you  might know!
