How do I amend my 2021 Illinois state return to claim the Earned Income Credit?

SOLVEDby TurboTax9Updated January 03, 2024

Some Illinois customers might not have claimed the Earned Income Credit on their 2021 state taxes, which may have caused an overpayment of their Illinois taxes.

To find out if you’re owed an additional refund, compare your refund/balance due amount from your original return with what you see now in TurboTax. Sign in to the TurboTax account you used to prepare your 2021 tax return. If your refund/balance due amount has changed, we recommend you amend your state tax return.

To amend your return, follow the instructions below.

  1. Note the original refund or balance due amount for your Illinois income taxes. We recommend you check the paper/PDF copy of your return, or your banking records, to verify the correct amount.  
  2. Sign in to the TurboTax account you used to prepare your 2021 return.
  3. In Tax Home, find Your tax returns & documents, and choose 2021.
