I'm being audited. 6a social security benefits is $61918, 4b IRA is $54128, 5b pensions is $76592, what should the 6b amount be?

It would be extremely unlikely that the amount on form 1040 line 6b would be anything other than $52,630.

Up to 85% of Social Security becomes taxable when all your other income plus 1/2 your social security, reaches:

Married Filing Jointly: $32,000

Single or head of household: $25,000

Married Filing Separately: 0

To see the Social Security Benefits Calculation Worksheet  in Turbo Tax Online version you would have to save your return with all the worksheets to your computer.   Or if you are using the Desktop CD/Download Software you can switch to Forms Mode (click Forms in the upper right) and click on SS in the list on the left side.
