Stimuly payments

I have not received any stimulus checks till date. I am guessing that it is due to my non filing of 2018 & 2019 returns. I am doing those 2018 & 2019 returns together now by sending the returns in mail. 

 

As per the advice from TTLC, I am going to e-file the 2020 return today for getting the 3rd stimulus check.

 

Is there a place in Turbotax to mention that I haven't received any stimulus checks? Do they process and send the 1st and 2nd payments as well?? Is it too late for the first two payments?

 

Please let me know
