Am I still under a stay with my creditors if my job did not take out the payments on time?

You have the automatic stay so long as no creditor asked for relief from the stay, and your case is still active. You may want to meet with a lawyer face-to-face. Answering questions here is like calling a doctor over the phone, whom you have never met, and then asking questions about your medical file, test results, and x-rays.

The bankruptcy stay starts immediately upon filing and remains in effect until the case is discharged or dismissed. An individual creditor can ask the court to have the stay lifted for good reason but you would receive notice of the filing.

The key question is not whether your employer send Plan payments on time. It is what the BR Court has or has not done. If it has not dismissed your case and not granted relief from stay to some creditor, then the stay should still protect you.
