Normally they are not split out on the financial statements since the total amount of the meals is entered into the tax return and then the deductible portion is calculated.
If you want to reflect it on your financial statements - normally non-deductible expenses would be listed as "Other Expenses". So you would have your net income then other income and other expenses.
The general journal entry depends on what you have entered to this point. If you are reporting the payment it would be:
debit Non-Deductible Meals & Entertainment (an other expense acct)
credit Cash, Credit Card, Checking account
(depending on how the meal was paid for)
If you already posted to the total to the deductible meals and entertainment account, the general journal entry would be:
debit Non-Deductible Meals & Entertainment
credit Meals & Entertainment (the deductible acct)
