I would just  have client paper file it, give it to the client and have them put a check in envelope and mail it. 

True, but client lives in another state... Not sure they even are able to download the form!

"wondering if it can be done electronically on their website."

What did you find when you looked?

Looked like "no."   I'm going to call in the morning..

What I meant was you preparing the form on the software and printing it out. If the client is out of state then send it to him via email scan file.

Per call to WV, they honor the federal extension.

Payment can be made on line.   Payment will be "floating out there" until return filed
