you don't get your money back, but you do get to uses it on next tickets to park or whatever. Esp. if you site covid as the reason, ...actually I don't know if one needs a reason now that I think about it. That's what others who canceled used, but it was the actual reason.
I bought a ticket for the 09/17 Boo Bash the day before. I got it at the Epcot International Gateway guest services when I activated my AP. You can check at any ticket window/guest services including Disney Springs.
