How do I remove a balance forward on an account? It shouldn't be on this account and I don't know why it is there (I am generating invoices now and this balance forward came up on the account for $105.73)

If you want to disable the balance forward feature for an account then go to Options | Billing and set "Display Balance Forward on Invoice" to "Use customer-specific option". Then edit the customer, go to their Billing tab, and uncheck "Display balance forward on invoice."
If you're trying to determine why they're showing a balance forward, then go to customer list, right-click on the customer and click "Print History Report". Set the date range far enough back to include all of their payments and invoices. Then you should see which invoice or payment is causing the problem.
