Retirement tax questions

If that is the case, how do you account for the second IRA if you don't have a corresponding 1099-R even though the aggregated RMD is satisfied?

 

Example: IRA-A distribution $10,000, RMD $2,000  1099-R received

                  IRA-B distribution  $0 RMD $1,000 no 1099-R

 

The RMD is satisfied for both accounts as the distribution was $10K, but how do you acknowledge the IRA-B to the IRS in TT without a 1099-R?
