Need Help: Sent Form 3520 via USPS now I can't E-File 1040

Per guidance in a few places including this forum, I mailed my Form 3520 vis USPS, since it is required for foreign inheritance over a certain amount. 

Form 3520 is not in my TurboTax file, however I do have a Form 8938, and in Part IV "Excepted Specified Financial Assets"  I've entered that I've submitted one Form 3520 (This was mailed via USPS).  Unfortunately TurboTax is telling me I can't E-File because I have a Form 3520!

I'm fairly sure that on Form 8938 I need to specify that a Form 3520 has been submitted.

 

Is this a bug? Am I doing something wrong here?

 

Thank you for the help
