HOW TO FILE EXTENSION ONLINE WHEN SPOUSE ALREADY WENT ONLINE AND MADE A PAYMENT?

I was planning on doing the tax payment when I filed the extension.  However, he went online and set up his short-term payment plan before I had filed the extension.  If I go online and try to file it, it of course wants me to make a payment or set up the payment plan. If I do make another payment and enter his same info, will it take out payments twice?  Is there a way to just file the extension without a payment?  Thanks!
