{Tax Year 2020] My IRS transcript dated 3-23-2021 has a 570 code dated 4-05-2021 and a 571 code dated 4-12-2021. Why future dates?

I e-filed 2-13-2021, still waiting for my refund.  My IRS transcript is dated 3-23-2021 and shows a 570 code dated 4-05-2021 and then a 571 code dated 4-12-2021.  Why these future dates?  How can there be a good news 571 code that shows up now, prior even to the 4-05-2021 570 code date?
