Hi there, @fsegoria, and welcome to the Community space.
Allow me to share some insights about your concern, why doesn't the Donor name portion show up for deposits included in a bulk split deposit even though I selected a name in QuickBooks Online?
Before we proceed, may I know which report you have already run? In case you haven't yet, you can run the "Transaction Detail by Account Report" to show the Donations Account. Please customize the report by adding the account in the column and unchecking the split to avoid any confusion.
Here's a photo as a reference:
