How to enter Non deductible expenses?

I have expenses I paid for out of my company account, which is not deductible.  These aren't your typical 50% of meals. These are things like an entire meal that I don't proper documentation for so I'm not going to deduct it at all.  Since I'm doing a balance sheet this affects the income reconciliation.  

I've read that using forms mode I can just adjust the values, however, in order to adjust the retained earnings, I have to click the checkbox that prevents M-2 from being filled out.  So I'm sort of stuck since I assuming I need to fill out M-2 since I have undistributed earnings in the companies bank account.   I'm new to all this so I might be missing something.  Thanks for your help.  Trying to get this thing submitted tonight.
