Be sure and leave the date blank on everything until the day you go to file.
I started filling mine out a month ahead and had to go back and amend the petition and all of the schedules because the date has to be the day you file or within a day.
The clerk's office sent a "Notice of deficient filing" and gave me a chance to do something about it. It didn't take long to fix, but it was a step that could have been avoided.
