Your answer is correct if you have only one IRA distribution and/or one Pension distribution and it is fully taxable. If you have more than one distribution, then there is a paragraph on page 29 of the IRS Form 1040 Instructions that reads:
"If you (or your spouse if filing jointly) received ore than one distribution, figure the taxable amount of each distribution and enter the total of the taxable amounts on line 4b. Enter the total amount of those distributions on line 4a."
TurboTax is not behaving correctly for multiple IRA/Pension distributions and you and the TurboTax Moderator keep missing this.
I can even tell you where the problem is caused in the TurboTax worksheets: This problem is caused by a broken link in the TurboTax worksheet "1040 Wks". The broken link is between Line 4 (Pensions and Annuities) and its data source (line 25 of the TurboTax worksheet named "1099-R Summary").
TurboTax needs to fix this, but I (and several others who actually understand this problem) are losing hope that it will ever get fixed.
