Yes, there is a way to post a one sided General Ledger entry to balance your accounts.  However, this feature should be exercised with care; I had tech phone support the first time I needed to do this.
 
DBA menu System Manager - UT-A
 
program name : EDITGL
 
then proceed to enter the $amt required to balance your General ledger accounts (however, I don't believe you can make an adjustment directly to the retained earnings account, since DBA internally post entries to retained earnings)
 
This program feature ONLY affects the General Ledger - (what you enter will not filter down to any other report  i.e. a/p aging)  
 
You may want to talk to Lynn.

Also, it sounds like part of your problem is an expense account that did not close properly to Retained Earnings.  UT-A, GLEREDO will recalculate all the YE closing entries.
