Form 8938 after efile

I start tax filling by free version of turbotax.
Turbotax is really easy and nice tool. Thanks !!

But I have one problem.

 

During the process, turbotax said I need to upgrade to turbotax delux to complete since I have foreign bank account.
I upgraded it to turbotax and just following the instruction, completed e-filed. But never navigated to Form 8938.

Question is
1. Do I still need to fill Form 8938 ?
2. If the answer is yes, how can I fill the form 8938 after e-fileing ?

  I searched this question on the forum, but can not find out the link to 8938.

3. If the answer for #2 is that I can not do filling 8938 form after e-filing.
   I  probably need to file 8938 by myself...
   Then, how can I refund my upgrade fee $60 ?

Thanks for the help.
