If you meet the Kelley Automatic DA criteria I believe you may be able to still enter as a Direct Admit.
“If you did not mark one of our Kelley undergraduate business majors on your IU Bloomington application, you may make changes to your submitted application by visiting Step 2 on the IU Office of Admissions website. This change may take 7 – 10 business days to process.”

If you meet the requirements email diradmit@indiana.edu to ask if it’s too late to switch. If you email the IU Office of Admissions you’re liable to get someone who doesn’t know what they’re talking about. This is actually a good lesson for anyone entering IU as a standard admit. IU is huge university and don’t assume that anyone (advisers, counselors) who don’t work in Kelley have any idea what’s going on inside Kelley.
