How Do You File Articles of Incorporation?

To file my first fictitious name statement, I need to file it with the County Clerk Recorder. You have to research the business name to see if it is taken, and I am researching my writing company, Tough B, Inc.  But due to COVID, the county clerk is not providing walk-in service or online service although you can print the application, fill it out, and then mail it.  There are filing fees to mail, and then newspapers to send the name to. My name is so unique I turned up no results when I searched.  It is up to me to get printer paper since I have an ink cartridge that will work when I install it.  I plugged in my printer again only recently, and have papers to file.
