Hello @infoithc.

It's nice to have you in the Community. I can help with filing a 1099 for your vendor. 

Since you've referenced that the vendor is already set to be tracked for 1099 payments, this is likely related to the mapping of the expense accounts. I'm including an article which includes steps for resolving issues with this form: 1099 Troubleshooting. I suggest looking at the section 1099 vendor is not showing on the list when preparing 1099s. 

I'm confident this resource will help to prepare the form and get you back to business.

I'd be glad to provide further assistance should you have any questions or need anything. Cheering you to continued success.
