Enter RMD data but line 1040-4a only shows Pension data, not the sum of Pension and RMD data..

If all of your IRA distributions are fully taxable, the IRA distributions will be included only on line 4b, not on line 4a, due to the convoluted instructions the IRS has provided for line 4a.

The IRA instructions for IRA Distributions read"Except as provided next [a list of 4 exceptions], leave line 4a blank and enter the total distribtion (from Form 1099-R, box 1) on line 4b."

I.e., If you have 1099-Rs for both IRA and annuity distributions, you may end up with a larger amount on Line 4b, than on Line 4a, but this is okay because it agrees with the IRS Instructions for Form 1040. This was my situation.

[wizestep]

Correct, although confusing.  It was my situation also.  If you just look at the form, it appears that 4b could not be larger than 4a, but it can and is if you have both pension/annuity and IRA distributions.

For me, 4a or 4b are forced to 1 and they are left blank.  Makes no sense.

@FrankV1   What is your full question with details?  You have added onto a very old post.  Several years old post.    What year are you asking about?  There will be many updates to come for 2021.  

[FrankV1]

My mistake. I didn't look at the date before I posted. Problem is current (2021) tax.

Except as provided in the exceptions listed in the Form 1040 instructions (see page 26), leave line 4a blank and enter the total distribution (from Form 1099-R, box 1) on line 4b.
