Recovery Rebate Credit - 2nd st

I received the first economic impact payment, but not the 2nd. The 2nd was based on 2019 income and i didnt qualify. I lost my job in 2020 but i filed that tax yr after that 2nd eip was already based on 2019. I thought i could get some of that 2nd payment but it looks like the Recovery Rebate credit is only if you didnt get that 3rd payment.  I got the 3rd one.  I know I read somewhere that i would be able to get part of that 2nd one but i guess not. I received none of it and was unemployed after early April 2020. EIP 2 shouldve been based on my 2020 income.
