I can lend a helping had to get this 1099 report issue sorted out, @neyerbj.
When pulling up a 1099 report in QuickBooks Desktop, the date range will default to the Last Calendar Year. Be sure that the report is set up for the correct date range next so it will display the right amount of information.
To give you more details about running a 1099 report in QBDT, please see this reference: Which contractors need 1099s?
On the other hand, there are a couple of reasons why vendors who are 1099 eligible are not showing up on the report. Only vendors you paid via cash or check should be reported, and only if the payments total $600 or more (It's up to you whether to report anything below that).
If you entered a check for payment but used Paypal as the check number, it will be ignored. Also, you should check the mapping of your accounts. If the account you used when you entered the bill or paid the vendor is not mapped correctly no payments will show.
However, if the information and mapping of accounts are correct and the problem continues, I suggest performing the steps found in this link. It provides different instructions to locate the 1099 vendors for them to show up in the report. Just follow the QuickBooks Desktop steps: Fix missing contractors or wrong amounts on 1099s.
Let me know on how things work. I'll be right here to provide further assistance. Have a good one!
