I've never filed for an extension, but I believe you're to estimate the amount you will owe in federal taxes when you file. If your husband is having taxes withheld in ample amount, and you're expecting a refund, maybe the extension form is requesting the $200 as a buffer for what you may owe. I'd have to know a lot more about your individual tax return before I could answer.
If you've already almost completed preparing your return in TurboTax, you should have a general idea of whether you'll owe additional taxes or not when you file.
It DOES get quite confusing. Do you have the $200 to pay when you file for your extension? If not (and you're fairly certain that you'll be receiving a tax refund), you don't HAVE to pay the $200. You can file for extension without making any payment at all.
