How do I eFile state after originally printing in desktop TT

I originally elected to print my MA state taxes using Turbo Tax desktop, now I would like to eFile.

The TT printed tax doc says "You can still file electronically.  Just go back to TurboTax, select the File tab, then select the E-File category.  We'll walk you through the process."

 

I've already successfully eFiled my Fed taxes.  The walk through doesn't appear to offer a way to select eFile for just the MA taxes.  What am I missing?

The Turbo Tax Help in the program has a FAQ that says:
"How do I change from mail to e-file in the TurboTax CD/Download software?"

 

This sounds like exactly what I want.  The provided answer also is tantalizing:
"If you changed your mind and want to e-file your tax return(s) instead of printing and mailing you can do so as long as..."

 

Unfortunately, if I click on the question to see the rest of the answer beyond "as long as..." I get "We couldn't find that answer for you."

How do I eFile MA after already eFiling FEDs?  Or is that the rest of the "as long as... you haven't eFiled your federal taxes" answer?
