I've got some information regarding the amended 1099 using QuickBooks Online (QBO), Amanda.

If you e-file your 1099 forms using QBO, after January 2024, you can submit your amended 1099 forms via QuickBooks Online, QuickBooks Contractor Payments, or QuickBooks Payroll. Since this feature will be available after January 2024, there are no further instructions yet. 

However, in all other years, and if you need to change your information immediately, you'll need to amend your 1099 manually to the IRS. Use these IRS instructions to do so. After the 1099 is corrected, you'll need to provide the corrected return to the recipient or contractor yourself.

You can access this material to learn more about how to make corrections to 1099-NEC or 1099-MISC forms after you e-filed them: Correct or change 1099s in QuickBooks. 

Furthermore, if you want to print your 1099, you can refer to this material: Print your 1099 and 1096 forms. 

If you have further information or concerns, please leave a comment below. I'm always around to help.
