After you file

So after speaking with the IRS on Thursday to see what was going on with my stuff, the lady I spoke with told me the computer has ran into and error which was no fault of mine and was trying to correct itself. I guess it finally did as my transcripts finally appeared. With regards to that, I have a few questions;

1) I have a code 150 and a 570. Is that a good thing?
2) I have a cycle date of 20191305. What does that mean?
3) It shows a processing date of April 15. Does this mean it won’t be processed until then?
