If this is CA then you will be mailing your return this year if you have a Sch C ... thank the fools in your state congress for this mess. 

OMG, you are kidding, right? where did you get that info??

Generally, if you are not able to e-file your return it is because your state has not opened up the e-filing option yet. Even though the IRS has started to accept e-filed starting 1/27/2020 there are some states who have not finalized their tax forms yet, thus not opening the e-file option.

Once the forms are ready you will be able to e-file your return and check the status here: https://ttlc.intuit.com/community/return-status/help/how-do-i-check-my-e-file-status/00/25538

Take a look at all the unsupported CA  forms for efiling this year ...https://care-cdn.prodsupportsite.a.intuit.com/forms-availability/turbotax_ca_windows_individual.html

California Schedule C and 8829 cannot be e-Filed for the tax year 2019.   Due to the recent tax law changes in CA on who is an employee vs contractor they want these forms mailed in.

In May 2019, the California Office of Tax Appeals ruled very recently that income from California-based clients is taxable as California source income.

The best source for current information is at this link: TurboTax State Forms Availability.

When it reads unsupported under the e-File column, taxpayers who need to file these forms will have to mail their returns. 

At this moment, I'm trying to submit e-file both state and federal; however, the state tax cannot be e-file. However, it doesn't note what the isssue is. How can I resolve this? I have not made any changes are added additional forms from the previous year. Thanks. 

It won't allow me to finish State taxes

You posted on a very old thread. If you are unable to file it may be because one of your state forms are not yet ready or unavailable for the e-file option. Please see the links below for more information about your specific federal and state form status:
