I already filed my taxes then got a 1099 -NEC in the mail, late. How do I amend that into my 2021 tax return?

Your return, you have to wait until your return has been fully processed and you have received your refund. Then you can prepare an amended tax return.

1. In TurboTax, scroll down to Your tax returns & documents. Select Show and then select Amend (change) return, and then Amend using TurboTax Online. (If you don't see Your tax returns & documents, select Tax Home on the left.)
2. Select the reason you’re amending and follow the instructions.

When you receive form 1099-NEC, it typically means you are self-employed. To add form 1099-NEC:

• Log in to your account.
• Select Federal from the left menu.
• Go to Wages and Income then select Income and Expenses.
• Go to Self-employment income and expenses and click start.
