Retirement tax questions

I am seeing the question "Enter the value of Roth IRAs on Dec 31, 2021". 

 

1.  I have made 10 years of "Backdoor Roth contributions" in one Roth account and 6 years of "Backdoor Roth contributions in my second Roth IRA. Is this question asking for the total balance of both of my Roth Ira accounts on 12/31/21?

 

2. What is the purpose of asking the total balance of these Roth accounts, since the values of each account varies depending of market ups and downs?
