After you file

I also order my transcripts to see dosen't have ddd. it shows the codes of all my credits for w-2 and additional credits and has a date of April 15, 2019 next to them, then I it has 2 more codes which are about the letters they  sent and it has the date of 3-4-19 and -3-11-19 next to them.
it also has that my return was received 3-4-19 and a cycle date of 2019-07-05 someone explained to me cycle date it means my return is processed on weekly biases Thursday is my process date so it will update on Saturdays for me if it does.. I don't see how it has 3-4-19 as received date when I filed and I was accepted on 1/28, it has a code of 971 and I looked that code up code be 100 different things it just say miscellaneous. so idk..... I'm so confused
