"Enter the value of Roth IRAs on December 31.2021"

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

 

1.  I have 2 Roth IRA accounts. I made 6 years of "Backdoor Roth contributions" into my first Roth account and 10 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, if the values of each account varies greatly depending on market ups and downs?
