Good day, @wcoryell. I'd be glad to share with you the steps on how to correct your filed 1099 NEC in QuickBooks. 

Since you've filed your 1099s in QuickBooks Online, you may be able to correct 1099s directly in your product. 

To start, ensure that that the IRS accepted your 1099s. To confirm:

1. Go to the 1099 filings tab
   1. QuickBooks Online and QuickBooks Online Payroll: Go to Taxes, then 1099 filings.
   2. QuickBooks Contractor Payments only: Go to 1099 filings.
2. In the Status column, look for Accepted.

Once done, follow these steps to E-file your 1099 correction:

1. Go to the 1099 filings tab
   • QuickBooks Online and QuickBooks Online Payroll: Go to Taxes, then 1099 filings.
   • QuickBooks Contractor Payments only: Go to 1099 filings.
2. Click Correct next to the form you want to fix. Please note that your business info must be the same as the original file accepted by IRS. If you’ve made changes since you filed, change them back.
3. The accounts and boxes you previously chose will appear. These are the accounts that represent the payments or expenses you paid to your contractors, and the corresponding 1099 box. To delete an account select Remove next to the row. To add or change an account select Select accounts.
4. If you want to change the 1099 box, select the dropdown ▼ next to the account and select the 1099-NEC or 1099-MISC box that represents the type of payments made to your contractors.
5. Select Next. If you make any changes to your accounts or 1099 boxes, you’ll get a message that other 1099 forms may also be affected. Check your other contractors' 1099 forms and fix if needed. Select Got it to continue.
6. Verify the Corrected total is what you expect. If the contractor payment total is now below the 1099 threshold, and they ‌no longer need a 1099, the Corrected total will be $0.00.
7. Check your contractors' personal info and email addresses. Select Edit ✎ to make any changes. Click Next.
8. Select Preview to view each corrected 1099. Click E-file corrected form twice.
