There are a few manufacturers having this problem. The IRS assigned them codes that do not meet the software's required format of Letter-number-letter-number. For instance, Mine is Weil-Mclain. The legit code is 46H2. I don't know how long it's going to take to fix the bug in software, but I have tried other avenues, and haven't found one yet that allows me to continue to e-filing.
If anyone has found one, please share here.
Thank you!
