Welcome to the Community, @adminloop.

I'm here to share some information about the amended filing feature for 1099s.

Upon checking here on our end, we don't have an exact time for the available amendment but for sure it will be available after January 2024.

For now, please refer to the IRS general Instructions for Certain Information Returns for the information that you'll need to prepare. Additionally, you can visit this link for more details about this process: How to correct or change 1099s in QuickBooks.

Also, the due date for submitting an amended return is generally within three years from the original filing deadline or within two years from the date the tax was paid, whichever is later.

For your reference, you can also check out this article for more information: E-file through the 1099 E-File Service.

Please keep in touch with me here should you have any additional questions about filing 1099s, I want to ensure your success. Take care!
