I appreciate for updating your QuickBooks, @Vikki18.

I want to make sure you're able to see the 1099 report, so you can direct it to the correct boxes in QuickBooks Desktop.

Since QuickBooks is in the latest release, ensure that the 1099 accounts are map correctly. This way, you can designate the correct report to the boxes. For the complete steps, visit this article: How to modify your chart of accounts for your 1099-MISC and 1099-NEC filing. 

As my peer mentioned above, generating a backup copy of your file is a component of the 1099 process. Also, to make sure you have a copy of your old data. 

When clients are missing from the list when mapping 1099, it could be because they're not active, marked as eligible for 1099, and the threshold is below $600. With this, I'd suggest checking the vendor's profile. To do this, please follow the steps provided by MaryJoyD. 

If the issue persists, I'd recommend communicating with our Customer Care Team. For the steps and support hours, you may refer to the article presented by Jen_D. 

Please note that the form 1099-NEC due date is February 1, 2021. Guarantee to submit the form before due dates to avoid getting penalties. For more details, you can check this article: Tax year due dates.
