If you already filed, wait until CO processes your return. If they include it, which they may, you won't need to do anything. If you get your refund and the $800 was not added, you can file an amendment and add it. If you have not filed yet, go back to your CO return and click through until you come to the TABOR (Colorado sales tax refund) question.
To qualify for the Colorado sales tax refund, your return must be postmarked by April 15, 2024 (or by October 15, 2024, if you file an extension).
