I think there's a bug. It keeps telling me to update my Utah withholding ID, and make sure it is 14 characters long without hyphens. I've done that. No dice.

I've found the correct Box, verified it's entered correctly, and it just won't work.

According to the Utah tax agency's website, the State requires a very specific format for the withholding account number:

FYI: Withholding Account Number

The Utah withholding account number is a 14-character number. The first eleven characters are numeric and the last three are “WTH.” Do not enter hyphens. Example: 12345678901WTH.

If form W-2 or 1099 does not include this number, contact the employer or payer to get the correct number to enter on TC-40W, Part 1. Failure to include this number on TC-40W may cause your withholding to be disallowed and delay any refund.

See here for additional information from the Utah State Tax Commission. Check with your employer to verify the number.

...and in prior years, the final WTH had to be entered in capitals......lower case caused a problem.

I'm having this same issue. Format is correct, as is casing.

@tccastaldo

Well, try it again, but use the other "Case"........we've gone back and forth on this so much, that now I can be confused as to whether UPPER or lower case is required !
