Hello there, @Anonymous.
I'm here to share some information on how QuickBooks handles deleting your donation receipts.
With QuickBooks Desktop, currently it doesn't have the ability to let you delete a large number of transaction records (such as donation, donation receipts, checks, inventory adjustments) or list records (such as items, customers, donors). What you can do is to manually delete each donation receipts one-by-one.
Just a heads-up though, there's no undo button after you've deleted your transactions. Thus, always create a backup copy of your QuickBooks file before you do any kind of major changes such as deleting your donation receipts.
For a more detailed instruction, you may check out this article: Void or delete an invoice or other transactions.
