Sorry you're stuck but there's almost always a pretty easy fix! Do NOT try to start all over again, eg. uninstall Max's Pitch Package, etc. That can make things worse.

I completed all the steps starting from 1-78 but in return, I ended up getting a blank pitch. Which wasn't supposed to be part of the plan. P-000 and P-005 are supposed to show up here; instead they're on the Pitch Everything List. How can I transfer two pitches to an empty one?
Not sure what you’re trying to do but no you don’t want to transfers any Pitch records. Hopefully you graded Lab 1a before starting 1b. The instructions emphasize you grade each lab before starting the next one. So you shouldn’t be concerned about those Pitech records from 1a anymore. When you started Lab 1b you deleted all your 1a work. So that old Pitch object and all the records you added with made up data should be gone. These records you’re showing here are the ones you imported into the new Pitch object you added by installing Maxs Pitch
Package. They all belong there as shown.
