Calculation of AGI (Form 1040 Line #11)

Hello,

I am seeking guidance on the what deductions can be taken for calculation of AGI Form 1040 Line #11 for my situation. Turbo Tax is calculating my AGI as follows:

-AGI is W2 income (box #1) and 1099 INT income

-AGI is only reduced by contributions to a 401k retirement plan

 

Question: Can AGI be reduced by the following contributions pre-tax? FSA Dependent Care, FSA Medical, HSA Account.

Can AGI be reduced by the following contributions post-tax? IRA (post-tax contribution to federal maximum rolled over into back-door Roth) and 529 Contributions.

 

If AGI can be reduced by the pre and post tax contributions listed above, why is the software not adjusting as such?

 

Thank You
