Hello @Anonymous, 

Thanks for joining us and sharing some detailed information regarding your concern. I've noticed a new thread you've created with the same question. 

My colleague @Charies_M was able to grab it and provided a helpful response specifically to the version of QuickBooks (Desktop) you're using. Let me route you to that link:

I want to ensure you're able to print out year end donation statements/letters to your customers, so please feel free to let me know how it goes.
