I can assist you in learning how to view your 1099 form from the previous year.
Here's how:
Select Taxes, then Payroll Tax.
Select the Filings tab.
View your current tax forms in the ACTION NEEDED or COMING UP section. Or select Resources, then Archived forms and filings for past forms. If available, select Preview to view forms not yet filed.
Since your contractors weren't able to receive their 1099s, I recommend directly contacting our QuickBooks Online Payroll Support for assistance with this matter. They will be able to provide you with more information and help you resolve any issues you may be experiencing.
