I don't have any MD S-Corps, but my first guess would be: did you set the refund for direct deposit or to receive a check?
Do you have other MD S-Corps filed yet (or in PY) that you can cross-check the e-file acceptance letters.
Also, "F4">"e-file log" might give some more details for added comfort around this.
