Your state police usually run the criminal report. In Oregon I had to go to the local sheriff and get prints. Then mail them off with a check to the state police. And since it needed to be an apostled report - that took a bit longer and cost a bit more. Arizona probably works in a similar manner.
I don’t think you can until 15 days after the first visa submission. Email them the return flight as they directed. It goes to your local embassy - so they work on your time zone
