Which code should the custodian of my Roth IRA have entered into Box 7 of my 1099-R?

 

In TY 2020 at the age of 56, I liquidated my $12,000 Roth IRA, which I have held for more than 10 years, to buy a first home.

 

Which code should the custodian of my Roth IRA have entered into Box 7 of my TY 2020 1099-R?

 

Thanks!
