Where you file a DBA in Navarro County depends on how your business is set up

Say you're opening a lawn-care business or a little bakery out of Corsicana and you want it to operate under a name like 'Pecan Street Goods' instead of your own. That trade name is an assumed name (a DBA, for 'doing business as'), and it's not a business license, just a public record that ties the name to a real person or company.

If you're running it as a sole proprietorship or a general partnership, you file the DBA with the County Clerk in the county where the business sits, so the Navarro County Clerk at the Corsicana courthouse, which keeps a form ready for it. But if you've already formed an LLC, a corporation, or a limited partnership, the assumed name goes to the Texas Secretary of State in Austin instead, and you don't double-file it at the county. The entity type decides the door.

A DBA also doesn't settle the rest of it. It won't get you a sales-tax permit, clear a zoning question on a storefront, handle a TABC permit if you're selling beer, or stand in for a professional license. It just locks down the name. Get the name on record first, then work the permits the actual business needs.
