Backdoor Roth IRA

During 2020, I contributed to my employer's Roth 401(k) and a Traditional 401(k).   In late-2020, I also converted a Rollover IRA (pre-tax money from previous employers) to a Roth IRA.  I'm assuming this is all taxable, but I don't understand how to answer the questions that TurboTax is asking. 

 

So I have traditional IRA's and Roth IRA's still active without any recent contribution or withdrawal activity... How do these enter into the equation? 

 

Do I have to worry about any 401(k) activity in my employer's account happening either this year or prior year?
