Retirement tax questions

 We entered an RMD and Conversion (from contrib IRA to Roth IRA) for myself.  These two show up on  line 4a and 4b.   Tried to then put in RMD for my wife and it went  to line 5B (total income)  I put them in in a different order and my wife's RMD will not go to IRA distributions line 4a or4b.   Have gone over questions multiple times.  This RMD does ask if it is a qualified pension (yes) .  Married is checked so two RMDs should be allowed.

Hope this clarifies what I tried to say before.  Thanks for your interest.
