One of my contractors does not appear when trying to prepare 1099 NEC. I followed all steps suggested by quickbooks help but they did not solve the issue.

Let's make sure your contractor is active and set up for 1099 tracking, @veronicapiano. That way, they'll show up when you're creating 1099s.

Before doing so, can you tell me the exact steps you've taken to fix the issue? I'd appreciate it if you could tell me the exact process.

If one of the contractors you set up in QuickBooks is missing or not showing correctly when you create your 1099s, please consider these factors: 

• Make sure your contractor is active and set up for 1099 tracking.
• Only those contractors you paid above the annual $600 cash threshold get a 1099. 
• When creating 1099s, QuickBooks uses the expense accounts you mapped to report 1099 transactions. If your amounts are off, you may want to review the contractor payment transactions and accounts associated with them.
• Make sure also that the transactions created should be check. 

Please refer to this article that details the process of fixing missing contractors: Troubleshoot missing contractors or wrong amounts on 1099s.
 

Once everything looks good, you can start creating and filing 1099s in QuickBooks Online.

That should help you get the contractor added to the 1099 lists. Get back to me if you have follow-up questions about this. I'm always around here in the Community to help.
