I show more on line 4b than 4a but that seems correct per the 1040 instructions. I have an IRA with a partial rollover and fully taxable pension. For the taxable pension: " If your pension or annuity is
fully taxable, enter the total pension or annuity payments (from Form(s) 1099-R, box 1) on line 4b; don’t make an entry on line 4a."
