I'd be more than glad to help you look for a way to view the 2019 entry as individual transactions.
Certain reports list the transactions individually. What steps did you take to pull up the report? Was it through the Chart of Accounts? This would help me narrow down the issue and find out how you can view the entry as individual transactions.
In the meantime, we can do these steps to find out what's causing the issue.
One thing to look out for is how the 2019 entry was entered. Was it through a journal entry? If so, it will automatically show up on the report as a single transaction. You'll want to click it to open the record overview and find out what accounts are affected.
If it isn't a journal entry, did you include other accounts as well? In this case, ensure your view isn't in collapsed mode. In your report, simply click the arrow icon beside the account name. It'll expand and show a list of transactions affecting it.

Here are two articles that can provide some additional information about the Retained Earnings account:
