The efile option for the state of utah will not accept my employer state ID number. No matter what I do, it will not accept the 14 digit number.

Is it 11 numbers followed by the letters WTH? See this:

Utah State Return says my employer ID is not 14 di... (intuit.com)

Yes, that is the 14 digit number that I entered. Turbo Tax continued to reflect it as an error and would not allow me to efile the state return until I corrected the supposed error. Turbo Tax was wrong. Finally had to efile the federal and mail in the state.
