H&R Block is not a federal authority that makes or interprets tax law that can be enforced by "any" legal authority. So while what you've mentioned is valid and correct, on the legal front it's what the IRS says, not what H&R Block or anyone else (including you and me) says.
But overall, based on what I see, you do have a SCH E rental. However, understand that if the property sat vacant between renters and you did not use it for personal use for one single day of vacancy, then you have ZERO personal use days.
