I printed my Fed return but can't find where to print my State return

It depends.

Make sure you have started your state return.  

1. After you have completed your federal return, select State in the left black panel. 
2. Be sure you select your state and go through the entire interview section. 
3. If your state is not listed, select Add Another State. 
4. It will ask you to run a review of your state return when you are done.

If you have already gone through the state sections, you should be able to print by following the instructions in the link below.

Printing returns for mail

Good luck. I am having the same problem and it looks like this is a chronic problem for TurboTax. It is unclear to me why they don't facilitate this. I would say I am very, very dissatisfied with this. 

I would love ANY ANSWER ON THIS -- even Turbotax telling me that _--SURPRISE!!! -- WE CAN'T HELP YOU AND YOU'LL NEED TO CONTACT YOUR STATE TAX OFFICE TO GET A COPY OF THE RETURN.  This completely sucks. The online guidance not only is NOT HELPFUL, IT IS MISLEADING .... 

You can print a copy of your return by following the instructions here.
