If you start using QuickBooks mid-year, you can use these steps reflect Year to Date (YTD) vendor expenses so your 1099s are accurate at year-end. These entries will NOT impact your financial statements.
When you print your 1099/1096 forms or run the 1099 Summary/Detail reports the amounts will be reflected.
If these steps do not resolve the issue, you can read discussions and post messages and questions relating to your issue on the Intuit QuickBooks Community site for free or you can contact a technical support agent for additional guidance. Fees may apply.
