If I take the combined total of two IRA RMDs from one IRA instead of in each IRA, I don't have a 1099-R for the second. How do I report the second in Turbotax?

Example

RMD for IRA 1  $21000    Actual Amount $24000 on 1099-R

RMD for IRA 2  $3000      Actual Amount $0  (no 1099-R)

RMD for IRA 3  $10000    Actual Amount $10000 on 1099-R
