File 2017 final tax return for my s corp that is dissolving in Jan 2018. Do I need to file final tax return for 2018 again?

I incorporated an S corp on 11/27/2017 in California due to wrong advices from my CPA.  No income, only $700 dollars expense in 2017.  My S corp will be dissolved around 1/20/2018 (I have submitted short form dissolution to california FTB).  Can I just file FINAL tax return for 2017 tax year? Do I have to file any tax return again for 2018 tax year for period (1/1/2018-1/20/2018) assuming no income, no expense?  Thanks for answering my question.
