It's good to have you here in the QuickBooks Community, @lorena-theteenpr.

I'd be glad to share some details on how to adjust 1099 filings.

If you've already filed your forms, you can submit amended 1099 forms through QuickBooks Online. However, as of this moment, we don't have specific instructions to do so. I recommend checking this article to verify from time to time if the accurate steps have been published: Correct or change 1099s in QuickBooks.

Once the instructions are provided, you can follow the steps below to ensure the correct box is selected:

1. Go to Payroll and then select Contractors.
2. Choose Prepare 1099s.
3. Make sure your company name, email, address, and tax ID are correct and match what's found on tax notices or letters from the IRS. Click Edit to make any changes.
4. Select Confirm info and get started.
5. Click Select accounts and choose or confirm the accounts used for your 1099 expenses or payments, then hit Add. 
6. Next to each account added, select the 1099-MISC boxes that represent the type of payments made to your contractors this year. Hit Next.
7. On the Tracked for 1099 tab, place a checkmark next to each contractor who should get a 1099. Make sure ‌the contractors' info and email addresses are correct. Select Edit to make any changes.
8. If a contractor is missing, select the Not tracked for 1099 tab. Select Add to tracked list to add the contractor to the Tracked for 1099 tab, then select Back.
9. Review the Reportable total amount for each contractor selected, then select Next.
10. Hit Preview to view each 1099 and review the amount in each box. Select Continue to 1099-MISCs to view your 1099-MISC forms. Select Next.
11. Once done, click Continue to E-File to e-file your 1099s. Or select I’ll print and mail to print and mail the forms yourself.

Moreover, see this article to learn how to submit your 1099s again if your form is rejected by the IRS: Fix rejected 1099 forms.

I'm more than willing to help if you have any other 1099 queries in QuickBooks Online. I'll ensure your needs are taken care of.
