I entered my husbands social security and my social security in the same way but mine shows up as nontaxable. How is that possible?

It adds them both together.  It's only split out when you enter them.  How do you know yours is not being taxed?  Where?

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

Social Security is on 1040 line 5a and the taxable amount on 5b.
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 program you can switch to Forms Mode (click Forms in the upper right) and click on SS in the list on the left side.

Did you enter both of them on the same scree?  This one?
