TWS is very easy. Logon, click on option trader, enter symbol, click on ask, change price near to the model price and transmit to market.
Right click on column headers and configure. Add model price between bid and ask.
You are doing the wheel strategy as advertised. You sold puts and were wrong and took delivery. You are selling ITM calls to get flat. You then sell OTM puts continually if you think the market is going up.
