Payment Received - Missing Tax Return

Guys, 

 

I received a mail from California Franchise Tax Board for my LLC stating that they have received my $800 payment for my entity id for the tax year 2020 but they could not locate a tax return for the same year. 

 

This was the year I used TurboTax all by myself for the first time, prior to this year I used to go CPA for my taxes. I was under the assumption that TurboTax will file everything for me, perhaps I am missing something?
