Stimulus: One-Time Payment Or Multiple?

Hi,

 

I'm behind on my taxes so I haven't received anything yet, nor do I know yet if I'll even qualify, but nonetheless...

 

1) Are people only receiving one (up-to) $1200 check/deposit for the duration of the entire shelter-in-place period of time?

 

- Or are there more than one payment, depending on how long someone's been out of work or financially impacted?

 

2) Let's say my taxes were filed today, have I then forfeited any potential stimulus payments from March 2020 til now? Ie, have I 'missed out' due to the supply running out after so much time has passed without claiming any of it? 

 

- Or is it based on when the time-frame began that I stopped working, and the accumulated funds will be available indefinitely regardless of when I file my taxes?

 

Thanks very much for any clarification!
