It blocks me from completing e-filing with the message "Check this entry." It says "UT withholding ID must be 14 ch long (...)", even I had no error scanning my W2 pdf.

I am a UT resident, a full-time student hired by the school. The app keeps on saying that "UT withholding ID must be 14 characters long without hyphens, you must go back to federal W2 to update the employer state withholding ID." But there was no error when I scanned my W2 file and rechecked it over and over.
