My 1099 Form does not have anything listed for Box 15, 16,17 and 14 - even though I do file state taxes. What should I write?

Moreover, I have funds invested in my 401K that Turbotax has not asked about. This is my first year with a 401K account.

If you are an employee and meant W2, if you did not have state withholding these would be blank.  Your 401k info is indicated by the Check Box and Box 12 Code D.

If it was a 1099, once again you would only have state information if there was state withholding (this is rare).  If you had a solo 401k for self-employment, you can enter under Less Common Business Situations.

I don't have a solo 401K - it is through my employment and is at a different firm than where I have my 1099 form from (and where I do my usual investing)

[MaryK4]

The 401k information is on your W2.  If there was no state withholding, you can leave the boxes blank on the 1099.

You only enter the 401K from your W2, nowhere else.  It comes out of your paychecks pretax and has already been deducted from the wages in box 1 so you can't deduct  it again.  Notice that W2 box 1 is less than box 3.  

What kind of 1099 did you get?  1099R 1099B 1099Div etc.
