Single member LLC: California form 568

Hello,

 

I used Turbo tax (home and business version) to filed tax return for tax year of 2019. 

 

I have a single-member LLC in California, so I always reported the business income on the schedule C on the joined filing with my husband.

 

I just received a letter from California saying they can not find my tax return. Should I reply with the personal return information?

 

Or Do I need to file form 568? I have the SM LLC for a long time, this is the first time I got the letter from California.  It was not generated by Turbo tax software when I filed for the tax return. 

 

thanks for your help
