So I assume you are a Utah filer.
The TC-40W Payer ID has to be 14 characters long (without hyphens) and ends with wth (included in the 14 characters).
So if you are entering it correctly like that, but it's still producing an error, here's what a fellow user reported worked for him:
The following is strictly anecdotal, so I can't guarantee it works for everyone. That user said he went back and entered his W-2 (or 1099) manually and used lower-case letters for the wth instead of capitals WTH, and that it took it OK with the lower case. He also said that on printed copies of his return, it printed out in capitals.

@ SteamTrain Have you seen any other Utah users with this issue report if this trick worked for them or not?
