Super confused about Credits this year? Can i get any credits?

Lost job due to cancer in 2018 so been out of work. Wife is stay at home mom, so we have 0$ income

Didn't file for 2019 so missed the 2nd stimulus but received first stim $2900.

Our 2nd baby was born in Nov 2020.

We wont get 3rd stimulus until they get bank info so lets leave that out of  this discussion.

I'm just really wanting to find  the refund check amount.

 

 

So I know I Have to file to get Recovery rebate and was hoping you could check my math?

I don't think I qualify for EITC or CTC with no income right? 

I'm trying to estimate just the tax refund amount on $0 Income, no taxes payed with these variables.

 (not including 3rd stim or new upcoming child credit)

Is this what one would get in just the refund check?

 

I didn't get 1st stimulus for new Nov 2020 baby - $500

Didn't get second stimulus at all so 2 adults + 2 kids - $2400 

 

So Total refund $2900? Recovery Rebate only? Sound right?
