My 1099s say filed in QuickBooks but nobody received them. Document says efiled and mailed but no contractors received them.

Let me provide some information on how your contractors will receive a notification after the 1099 forms are e-filed, marcushayle.

Once you file 1099 form, we will email or mail a printed copy to your contractors. If they haven't received a copy yet, we'll notify you of your filing status through email after you electronically filed the form after you e-filed the form. You can view the 1099 and provide it to your contractors instead. To do this, you can follow the steps below:

1. Go to Taxes then select 1099 filings.
2. Select View 1099 to view a PDF copy.

However, if you didn't e-file them, you can print copies and send each to your contractor. For more information and detailed steps on how to create and file 1099s. check out this article for your reference: Create And File 1099s With QuickBooks Online.
