What the others above me said. The only thing to add is their probably wont be a "sell to open covered call" line. It will just be "sell to open" and the system understands that since you hold the equity it is a covered call. Note: while the option is open you cannot sell that stock since it is being held as collateral.
I am going to stress again please spend time learning about options before investing in them. Please. I know men like to not bother reading directions and just start putting shit together but in this case, you really want to understand this stuff. Make practice trades on paper and see how you do. Figure out what went right and what went wrong. After I screwed the pooch on BA options early in the year, I spent a couple of months doing just that. Fake options trades with fake money. Learn with monopoly money.
It doesnt get discussed enough here but if you are selling covered calls, make sure you also understand the concept and mechanics of rolling options.
