Why does the amount shown on Form 1040 line 4a differ from the information on the screen labeled Retirement Income Results?
When I look at Line 4a (IRA's, Pensions, and Annuities) of the Form 1040 it has $44,815. This is only the amount of Traditional and Roth IRA distributions showing on the Turbo Tax screen labeled Retirement Income Results.
On the screen labeled Retirement Income Results, I have two lines. The first is the information above. The second line is labeled Pension and annuity distributions. That amount is $20,314.
The total for the two shows as $65,129. This is the amount that I would think should show on Line 4a of the Form 1040
Then there is a Taxable column which takes the two taxable amount from the two sources and totals $62,463. This shows accurately on the Form 1040, line 4b.
"Except as provided next, leave line 4a blank and enter the total distribution (from Form 1099-R, box 1) on line 4b."
There are multiple exceptions listed ("except as provided next") in the text that follows, in which you are supposed to add the total distribution into 4a, not leave it blank as stated above. This means that sometimes the total distribution of an IRA/pension/annuity is added to 4a and sometimes it's not.
This was tolerable while IRAs were reported on one line and pensions/annuties on another (yes, this is the way it has worked for years), but in 2018 when the IRS redesigned the 1040 form, they lumped IRAs and pensions/annuities together on one line.
Now we see much more often that some of the total distributions are added to line 4a and some are not, with the result that 4a is sometimes smaller than 4b.
This surprises a lot of taxpayers, but it is exactly what the IRS instructions call for.
The TurboTax worksheet shows the actual numbers, but the form 1040 (which is the filed form) shows the numbers as the IRS wants them.
