Last year's FL Corporate Tax Report F1120 was not filed and I am just realizing this now, with a penalty. How do I find that? How do I submit that?

Was this for 2017? 

Print it and mail it to:

FL Dept of Revenue

5050 West Tennessee St.

Tallahassee, FL 32399-0135

Since there was a Federal extension, you could call them and beg for mercy, pleading Hurricane Harvey disruption. They may waive the penalty. 850-488-6800

I just received a letter from FL dept of revenue saying I didn't file and now I have to pay a penalty of 300 dollars. I thought Turbotax was supposed to file these forms along with the state taxes. Did you resolve your issue? How do I get this form? Is it the same 1120 form for the IRS? Thanks.
