Hello tloesing,

Thanks for giving us a lot of information. 

Since you've already entered the correct ending balance (when you started QuickBooks Desktop), we won't be able to show the $500 expense amount on the 1099 form (previously entered in the old system). If you'll enter the transactions, it'll affect the bank's balance. However, you might find one of these options helpful. 

• Option 1 is you can delete the beginning balance and re-enter the vendors' transactions. 
• Option 2 is you can create dummy expense transactions for these vendors and delete them after creating the 1099 form. This way, we're able to maintain the correct bank's balance. 

I also suggest asking for more help from your accountant. They know what will be the best thing to do so you can generate 1099 forms.

If you have any questions, please let us know.
