You guys should consult a lawyer for things like this. For the OP, my wife had a similar situation where she was caught and sent back after being fingerprinted and having her picture taken. For that reason, we consulted a lawyer and she had her fingerprints sent to the FBI. Long story short, nothing ever showed up in the FBI's system nor when she had to do the biometrics for DACA. She was able to clear her EWI with AP without a problem and she's now had her green card for a year.
