Can't e-file NJ return after extension

[denchm]

I filed for extension for Federal and NJ return. 

TurboTax allowed me to e-file my Federal return but says my State cannot be e-filed. My understanding was this was only if I was filing an amended NJ return. However I'm not filing an amended return (as previously I just filed an extension, not a return) so don't understand why TurboTax won't allow me to e-file?
