Hello there, @Endy.
Thank you for posting here in the Community. It's my pleasure to help run report in QuickBooks Desktop (QBDT) with all the donations amount in the previous year.
To see the list of all donations on the previous year you may switch the accounting basis to either cash or accrual. You can do it by choosing either Cash or Accrual beside Report Basis and Refresh the report.
Also, make sure that the date are filtered correctly.
Let me know how it goes by leaving a comment below, we're always here to help. Have a wonderful day!
