I have the same problem--never received the second Stimulus payment. When I look online, it says my 2019 was not received but they cashed the check I sent with it. I was able to get someone from the IRS on the phone (after a 30 min wait)--he said they have just started processing my 2019 return and I should give it 3 weeks. My 2020 return has been rejected 3x--they keep asking for my AGI from 2019, then saying the number I gave them is incorrect, even though I took it right off the form. I'm guessing they can't accept 2020 until they finish processing 2019? Problem is I really really need that stumulus!!!
