Hi there, @nikkibeth12.

Let's first remove the contractor who doesn't have an SSN. Then, e-file the 1099 form of the other contractor with SSN.

Before we proceed, please know that the IRS requires you submit 1099 with SSN information of your contractor.

Here's how:

1. In your QuickBooks Online, click Expenses from the left menu, then select Vendors.
2. Select the appropriate vendor from the list.
3. On the vendor's information page, click Edit.
4. In the Business ID No. section, uncheck the Track payments for 1099 checkbox.
5. Click Save.

Once done, you can now prepare and e-file your contractor's 1099 with the SSN information. For your reference, you can check out this article for more guidance: Prepare and file 1099s.

Also, for the contractor who doesn't have an SSN, you can manually file or mail the 1099 form outside QuickBooks to the IRS. But as mentioned by @Rustler above, you should have a vendor that filled out and returned the IRS W-9 form to prevent this in the future.

Please touch base with me here for all of your QuickBooks needs, I'm always happy to help. Have a good one.
