ToS: Did I place this call option correct? (My first covered call)

I know what it means to sell a call option in principle but this is the first time I've sold a call option on ToS so I wanted to know what to expect when the option expires.

Context: I bought 430 stocks of UAL last October at $34.75/sh. I believe its value will appreciate and am willing to sell at the strike price of $62.5/sh. I figured I can make some extra money by doing a covered call: if, by Jan 2024, the price doesn't reach $62.5/sh, I'd keep the $800 premium. If the option gets exercised, I'd be able to sell at the price I want and keep the premium. By expiry date, mid Jan 2025, it would have been a year so profit would be taxed at LTC gains (yay!)

Question 1: See photo. Does the information for the call option look right (in that it represents me selling the call option)? What is the value under the "Net Liq" column?

Question 2: Suppose UAL reaches/goes above the strike price on/before Jan 2024. If the option holder exercises the call option, will ToS automatically sell 400 of my UAL stocks at $62.5/sh to the option holder? If so, how much should I expect in proceeds - would it just be $62.5 * 400?

Question 3: Is it possible to sell my sell-call option?
