I didn't know there was a second extension.

Yes if the entity has paid more than $10,000 in franchise tax in prior year is only extended until August 15th and can request second extension by August 15th to extend it further until November 15th. TX Comptroller Webfile has option to file second extension but we will have to manually include all affiliates, therefore, I was checking with ProConnect if it has option to request second extension. 

Thanks for the info. Sorry I don't know the answer to your question.
