I had the same issue. I worked for former Verizon now Frontier. I ended up mailing them in. Another employee just added the totals and put them under the Current employer state id. He efiled and it went through. I'm not advising this but it seemed to work for this guy
I worked for two California companies that are using Trinet. Consequently, I got a consolidated W-2 with the CA abbreviation listed twice (one for each employer) on line 15. For some reason, TurboTax prevented me from E-filing. So, I added the amounts on lines 16 and 17 and under Employer's state ID I listed them both separated by a "/". It seemed to work.
I have the same issue, but it's 2 separate companies that are both using TriNet, so I can't just add them together since they have different Employer State ID #s. Has anyone else had this issue and figured out what to do?
I'm not able to efile my CA return, even though I've already paid the $25. Why wasn't this checked by TT before I paid them?
