By definition, you can't have a year end without creating opening balances for the next year. If you just need to zero out all Income accounts to Retained Earnings, a journal entry would definitely be the best approach.

If there isn't an appetite to create such a JE from a Trial Balance manually, as I see it, there are a few options:
1. Export the TB to Excel and format into a JE import file
2. Write a macro to browse all income accounts from GLAMF
-for each account, lookup the balance at your cut-off and create a line in your JE
3 Read the balance of your JE and create a final entry to the Retained Earnings account.

Best of luck!
