I’m having a similar issue trying to pay for California e-filing using the Windows Premier version of the software. After clicking on “pay with credit card” the same “slight snag” message that you mentioned comes up. Never even have the chance to enter credit card information into the s/w. I too was on phone for hours with support and was led through the same actions as you - to no avail. I hope someone that knows what’s going on reads this. There’s over a month before the filing deadline, so it seems like enough time for Intuit to address this issue (and there’s a financial incentive to fix it too). If it comes down to it, I can print and mail the return but I really don’t want to do that!
