Retirement tax questions

When my husband passed in 2023, his IRA was $10k and a RMD happened for $4k.  Then my IRA was established and his $6k account balance was rolled into my new account.  I received a 1099-R in my name and SS# for $10k in both Box 1 and Box 2.  Box 7 is marked with a 4.

 

Currently on the Form 1040, there is $10k in 4a and $0 in 4b.  I will try changing TT 1099-R Box 2 to $4k.
