Filled in 1040 worksheet which has populated 4b on 1040 postcard, in agreement with amount but nothing fills in on 4a 1040 postcard, is this correct?

[Just-Lisa-Now- · Accepted solution]

I don't know my new line numbers yet, is that for retirement income?   

If so, and the gross and taxable are the same amount, you'll only see a figure on the taxable line, the gross line will be empty.
