My advice (after the fact and after a long learning curve) is that I would have taken a photo of the lot with the date and location on the photo to prove that I was there. One app that does that is Timestamp Camera. Whenever something happens that might need documentation, I take a photo of it. In the last year, I ran into banks closed due to an active COVID case (after they were allowed to reopen) and I took a photo of the notice on the door with the time, date, and GPS location on the photo. Same with the drive-thru closed when the inside was open (and the reverse).
I then submitted the report, using the photo everywhere a receipt was required. In every available text response area, I typed (and copied/pasted) an explanation of what happened. I used whatever response (Yes/No/NA) resulted in the easiest report to submit.

It was the correct lot; I verified with the signs and even asked the parking attendant if it was the right address.
